    Solution for bulk, short to long URL, redirects
    Hi, Please suggest any solutions how I may achieve bulk redirects I wish to use a Google sheet containing two columns. One column for the short Source URL, and the second for a long Destination URL. Each row would contain a separate individual website redirect.

    Understanding the Call Stack in JavaScript
    The Call Stack is a fundamental concept in programming that helps manage function calls in a program. Let's break it down in simple terms. The Call Stack is a special type of data structure that keeps track of the functions that are currently being executed in your program. It's like a stack of plates: you can only add or remove plates from the top. In programming terms, this is called a "LIFO" (Last In, First Out) structure. When a function is called, it is "pushed" onto the Call Stack. When the function finishes executing, it is "popped" off the stack. This process ensures that functions are executed in the correct order and that each function has its own context (variables, parameters, etc.). Example function greet(name) { return `Hello, ${name}!`; } function sayHello() { const…  ( 4 min )

    🧙‍♂️Beginner-Friendly Guide "Find the K-th Character in String Game I" – LeetCode 3304 (C++ | Python | JavaScript)
    Hey adventurers! In this playful string-based puzzle, we join Alice and Bob in an ever-growing word game. From just a single letter, a mysterious pattern evolves — and you’re tasked with figuring out what the k-th character becomes after repeated transformations. 🌀 Let’s demystify it together. You're given: A game that starts with the string word = "a" A number k, indicating the position of the character you want to retrieve Each round: Every character in the current word is changed to its next character in the alphabet, and the result is appended to the word. Examples: "a" becomes "ab" "ab" becomes "abbc" "abbc" becomes "abbcbccd" Your goal: Return the character at position k (1-based index) after enough rounds. If you trace the pattern carefully, you'll realize: The transformation is deterministic. Each new character in the word is one step ahead of its source. The position of each new character follows a binary-like structure — much like the count of 1s in the binary representation of k-1. Thus, the answer is simply: 'a' + popcount(k - 1) Where popcount(x) counts the number of 1s in the binary representation of x. class Solution { public: char kthCharacter(unsigned k) { return 'a' + popcount(k - 1); } }; class Solution: def kthCharacter(self, k: int) -> str: return chr(ord('a') + bin(k - 1).count('1')) var kthCharacter = function(k) { const popcount = n => n.toString(2).split('1').length - 1; return String.fromCharCode('a'.charCodeAt(0) + popcount(k - 1)); }; This elegant transformation can be reduced to analyzing binary patterns. Think of each bit in k-1 as a transformation step. No need to simulate string growth — bitwise logic wins here. 🧠 From a simple "a" to a cascade of characters, this problem rewards observation and pattern recognition. It's a neat reminder that clever math can beat brute force. If you enjoyed this one, share it with a fellow coder! Happy decoding! 💻✨  ( 4 min )
    Minimizing False Positives: Enhancing Security Efficiency
    Organizations waste enormous amounts of time chasing down security alerts that turn out to be nothing. Recent research from May 2025 shows that 70% of a security team's time is spent investigating alerts that are false positives, wasting massive amounts of time in the investigation rather than working on proactive security measures to improve organizational security posture. This problem is compounded by the fact that 33% of companies have been late in responding to actual cyberattacks because their teams were busy with these phantom threats. What is low false positive rate security? Accuracy is one of the top goals when doing any security work.

    Auth-as-a-Service is dead
    When I started building products, Auth-as-a-Service felt like a gift. Plug in a few lines of JavaScript, and boom! Sign-up, login, and password reset all taken care of. No more rolling your own sessions or wrestling with bcrypt. It felt like cheating (in the best way). But over time, something changed. Authentication stopped being the problem. It was connecting it to everything else around it. You still had to: Decide how users would pay Gate access to features after login Assign roles and permissions Customize onboarding flows Sync data to your CRM, analytics, and internal tools Handle cancellations, trials, and feature upgrades None of that lived inside your auth provider. So you ended up bolting on half a dozen tools, wiring them together with glue code, and praying it held up. Auth got abstracted. But the rest of the user journey? Still chaos. So what was the choice? Bolt on more yet more tools and then figure out how to get them to talk to each other and keep all the data in sync. That’s why I believe standalone Auth-as-a-Service is dead. The future isn’t just about logging people in. It’s about managing the full customer journey: That’s why we built Kinde as a platform, not just an auth provider. We started with authentication but always knew it was just the first piece. Today Kinde gives you: Authentication Roles and permissions Feature flags Billing (Stripe-powered) Workflows User management Custom data B2B management All working seamlessly together. All designed for SaaS builders. A fully integrated developer platform. If you’re building a product where users sign up, pay, and expect gated access you don’t need another 6 services - you need a platform. Auth-as-a-Service was great for 2015 but it’s 2025 now and it’s time to raise the bar.  ( 3 min )

That’s a lot of quiet confessions being made to something that doesn’t blink, breathe, or bench-press emotions. So… does AI have the chops to help us heal? Or are we outsourcing our mental health to machines that don’t quite “get” the human part? I don’t know about you, but the idea of talking to a robot about my deepest fears kinda makes me want to back slowly out of the room. But also—there’s a little part of me that gets the appeal. Round-the-clock access, zero judgment, no scheduling struggles, and it won’t…  ( 13 min )

    SaaS friends - Stop reimplementing messaging features 🛑 🫷🦺🫸 🛑
    Everyday, somewhere in the world, a SaaS product team reimplements the same set of messaging features A handful of the most common: 📝 Code and low-code template editors for email and SMS Consider the example of an app for healthcare providers: the providers may want to automate SMS to patients when a prescription refill is available. Or maybe there's an app for property managers that needs to let managers email tenants when a lease is up for renewal. It’s a non-trivial lift to build this suite of tools. Engineering teams regularly take 6-12 months to implement them, not to mention the ongoing maintenance requirements. Engineers' time is valuable, and a company's development speed is often it's greatest asset. If messaging software isn't your core business, building it is going to slow you down and take you off-course. So why not embed messaging in your app? Dittofeed’s Embedded Components wrap up features from its existing open-source messaging automation, allowing them to be embedded within your own application. Embedded Components can be consumed using styled iframes, unstyled react components, or by using Dittofeed as a headless API to rebuild your own components from scratch. There's no need to keep building this stuff. It's hard and boring.  ( 3 min )

    Understanding Node.js ABI Version: What It Is and Why It Matters
    “Ever encountered a cryptic 'Module version mismatch' error in Node.js when working with native addons like sharp or bcrypt? It’s all about ABI compatibility. Let's demystify what Node ABI versions are and why you should care.” In software development, an ABI (Application Binary Interface) defines how different components of binary code interact at runtime. This includes: Function calling conventions Data types and structures Memory layout Register usage In simpler terms, it’s the low-level handshake between a program (like Node.js) and a compiled binary module (like a C++ addon). The Node ABI version is a number assigned to a specific Node.js runtime version to indicate how native (binary) addons are expected to interface with it.

    Another good day to get some dev done! up at 6am with the daughter, got in some gamedev before work while she slept again. There's a cracking cool breeze. Work was pretty chill. Let's get cracking! Started overhaul of aesthetics Completed main menu Completed in game "hud" Completed spelling menu, not bug free, but minor layout fuckery. Completed game over menu Completed options menu, just a placeholder with a back button for now. But soon! Overhauled colouring within the game using a Theme manager to eventually cater different eye conditions and preferences. Accessibility isn't hard to at least think about early. Overhauled the grid, no more .png. generated at runtime. Opens up a whole bunch of potential and control. As well as it had to be done to work with the Theme manager. Created a lo…  ( 4 min )
    An easy way to stop Claude code from forgetting the rules
    You spend time setting up Claude Code with specific instructions in your CLAUDE.md file. Maybe you want it to always ask for confirmation before creating files, or to follow particular coding workflows. It works perfectly for the first few exchanges. Then something changes. By the fourth or fifth interaction, Claude Code starts ignoring your rules. It stops asking for confirmation. It forgets your workflow preferences. It's like your CLAUDE.md instructions never existed. This isn't a bug, it's how AI models work. Understanding why this happens and the simple solution discovered by a Claude Code engineer can save you hours of frustration. Large language models like Claude don't actually "remember" conversations. Instead, they read the entire conversation history as one long text document ev…  ( 6 min )

    Running a PHP Application inside a Container
    Hello 👋, In this month’s blog post I’ll show you how to run a PHP Application inside a container. I’m quite a fan of online forums and the majority of forum software is written in PHP. To evaluate them quickly I wanted the ability to be able to run and install then locally. I’ve come up with this docker-compose file: services: nginx: build: context: ./ dockerfile: nginx.dockerfile ports: - "8080:80" # change port 10080 to any other port volumes: - ./config/nginx/conf.d:/etc/nginx/conf.d:z - ./.data/nginx:/var/log/nginx:z - application:/var/www/html:z - composer:/root/.composer:z php: build: context: ./ dockerfile: php83.dockerfile volumes: - ./config/php.ini:/usr/local/etc/php/php.ini:z - applicati…  ( 3 min )

    How to create a QA checklist for regulatory-heavy fintech features
    In fintech, launching new features isn’t just about building cool tools – it’s about making sure those tools follow tough rules. For leaders in fintech, the challenge is clear: create a QA process that keeps up with fast development while making sure everything stays compliant and secure. The cost of mistakes is high – fines, lost trust, and delays that slow down growth. Regulations like PCI DSS, GDPR, and AML aren’t just paperwork – they mean testing things like secure payments, data protection, and audit trails. If the QA checklist misses these areas, the product is at risk. A Deloitte report says 60% of banks find regulatory rules are getting harder to manage. Capgemini’s 2023 FinTech report shows almost 30% of fintech startups face delays because QA and compliance take too long. Gener…  ( 7 min )

    Rethinking Postgres read replicas for modern workloads
    Read replicas have long been the go-to move for scaling PostgreSQL. But that doesn’t mean they're still the best fit for today’s workloads. Read replicas have been part of the Postgres toolkit for years. For many teams, they're the default way to offload pressure from the primary database. But as workloads grow and expectations for performance and efficiency increase, the traditional read replica model starts to show its limits. Postgres replicas work. They’ve helped countless teams move reads off their primary, improve availability, and keep critical workloads running smoothly. They’re a proven tool for: Offloading read-heavy traffic from the primary Isolating long-running queries or reporting workloads Providing high availability and failover options For many, read replicas are the first…  ( 5 min )

    I Got Tired of Build Tools, So I Built a JS Framework for Instant UI Prototyping
    Ever have an idea for a UI component and just want to see it in your layout, right now, without fighting with build configs, imports, or CSS class names? That frustration led me to build SlightUI, a tiny "boutique" framework with one main goal: to make UI prototyping as fast as thought. It's for developers who want to visually compose interfaces and see how elements fit together instantly. The core of SlightUI is a lightweight Express server that kills the traditional front-end build step. When you run the project, it dynamically scans your component files (/components/button.js, /components/card.js, etc.) and bundles them for the browser on-the-fly. What this means for you: Create a file: components/NewThing.js. Use it immediately: Write UI.NewThing() in your app. Refresh your browser.…  ( 4 min )

    Day 5: Connecting Everything with Django’s MVT Architecture
    Hi, so today I focused on understanding and applying Django’s MVT architecture, the foundation of how Django apps work. So what is a Model in Django? Django uses it to create tables automatically, based on your field definitions. It handles all data-related operations: Create, Read, Update, Delete (CRUD). For example in my previous project I added this kind of model. from django.db import models class Item(models.Model): name = models.CharField(max_length=100) description = models.TextField() created_at = models.DateTimeField(auto_now_add=True) def __str__(self): return self.name what is a View in Django? It receives a request, fetches data (usually from the Model), and returns a response (usually a rendered Template). I created a view to fetch data from the database and send them to the template: from django.shortcuts import render def home(request): return render(request, 'app1/home.html') So what is a Template in Django? A Template is an HTML file used to display content to the user. It uses Django’s built-in Template Language (DTL) to display variables, loop through data, and include logic. what are URLs in Django? http://localhost/products) to the correct view. URLs act like a bridge between the browser and the backend logic. User types http://localhost:8000/products/ URL routes it to view View calls the Product model View Model fetches data from the database Model View passes data to the template View Template displays data in HTML Template Part Django File Purpose Model- models.py Defines structure of database tables View- views.py Contains logic to fetch/process data Template templates/.html Displays data using HTML & DTL URL- urls.py Connects browser requests to views My Reflection on Day 5 Understanding how each MVT part plays its role helped me finally see Django as a full web framework — not just scattered files. Now I can create real, working web pages powered by Python and databases, not just static HTML.  ( 4 min )

    Why Planning a Project Is the Most Important Aspect of Building
    I recently set out to build an E-commerce platform using a Microservice Architecture. With a decent level of experience, I figured I could move fast: define a high-level plan, get help refining it, and dive straight into implementation. To speed things up, I shared my initial ideas—workflow, database schema, and API routes—with GPT, got a refined version, and started building based on that. In hindsight, this approach taught me a lesson I didn’t expect to learn at this stage of my career: no matter how experienced you are, skipping proper planning will come back to haunt you. After jumping into implementation, I began to realize that the schema I was working with had several gaps.

    Platform Engineering & IDP Quickstart: Deploying Backstage
    Engineers and technical leadership teams have three common goals: Increase efficiency. Reduce toil and effort on teams. Build better abstractions. Perhaps most importantly, number 3. Abstractions for everyone who needs to perform a particular job, but may not need to know what's going on underneath the hood. In this blog post, you'll learn about one of the most effective ways to accomplish all three - by using IDPs. Organizations want to “do the Kubernetes thing” because it’s the de facto standard across the industry. At the same time, technical leadership teams do not want to: Hire engineers who are just Kubernetes experts Spend time with a massive amount of training for engineers to get up to speed. And the majority of engineers don't need to know what's going on underneath the hood. If …  ( 5 min )

    I've just released my comprehensive document on System Design!
    Hey everyone, I'm Link! I'm excited to be a part of this community and share my first post with all of you. I've had some extra time on my hands lately, so I decided to create a comprehensive guide called System Design 101. In this guide, I'll walk you through building fundamental system components from the ground up, offering helpful tips along the way. I've kept the content abstract and free of specific code or software, so it's broadly applicable. Here's a glimpse of what you'll find inside: Web Services: Dive into the world of microservice architecture and discover best practices for creating scalable web services. Data Persistence: Get to know the persistence layer, understand the structure of common data stores, and tackle the challenges of distributed storage. System Administration: Learn about essential administrative tasks, key components, and best practices for maintaining and deploying distributed systems. Design Patterns: Explore the architectural patterns that are essential for designing large-scale systems. This guide is a big undertaking and is based on my own experiences, so there might be a few bumps along the road. I welcome you to contribute, share your thoughts, and help make this project even better. If you find System Design 101 helpful, I'd appreciate it if you could give the project a star on GitHub!

    Unlock the Web’s Hidden Stacks: My Solo Journey from Hackathon MVP to Open-Source project
    TL;DR Summary After building Open Tech Explorer in the Bolt.new hackathon, I’m now transitioning from a rapid MVP to a production-grade, open-source platform-complete with Chrome & Firefox extension support, a live contributor pipeline, and a roadmap for deeper analytics and mobile PWAs. Coming into demo day with a solo-built Chrome extension and a minimal React web app, I discovered how critical real-time, community-driven tech discovery is for developers and researchers. Under hackathon pressure, I wired together React, Supabase, and Deno edge functions-then deployed the site at openexplorer.tech to prove the concept in under 48 hours. After demo day, I found myself staring at mountains of raw scan data and realizing there was a narrative buried in every entry. That moment sparked my v…  ( 5 min )
    🐳 Understanding Docker Registry: A Friendly Guide for Everyone
    Imagine you’re a chef. You’ve just finished cooking your delicious signature dish. But instead of serving it immediately, you store it in a fridge so that other chefs (or even your future self) can access it anytime, anywhere. That fridge? In the world of Docker, it's called a Docker Registry. Let’s dive into this together and make it fun! 🎉 Docker lets developers package an application and everything it needs (like libraries, code, dependencies) into something called a container. These containers can run anywhere — on your computer, a server, or in the cloud — making development and deployment super smooth. But once you’ve created a container (or more specifically, a container image), where do you put it? That's where Docker Registry comes in! Think of a Docker Registry like a magical on…  ( 4 min )

    How Dynamic URLs Help You Test Content at Scale
    Traditionally, experimenting with images or videos involved generating and storing several versions, which can take time and storage space. Every new campaign or test variation meant uploading new files, which slows down creative workflows and clutters storage systems. This approach doesn’t scale well in a world where businesses must adapt quickly to trends, user behavior, or personalization strategies. Dynamic URLs allow teams to apply on-the-fly transformations to media assets using URL parameters. By simply modifying the URL, one file can serve endless variants. It can be resized, cropped, filtered, overlaid with text, or stylized, making experimentation both fast and lightweight. By leveraging this, developers, marketers, and content creators can instantly test different layouts, formats, and styles. Creative teams can experiment without waiting on developers or file uploads. Developers can build systems that automatically tailor content based on user context, like device type, location, or preferences, by dynamically modifying URLs at runtime. E-commerce: Show personalized product images with region-specific prices or seasonal backgrounds. Media & Publishing: Optimize images for different screen sizes and orientations. Marketing Teams: Run quick visual tests with different headlines, CTAs, or badges without creating new assets. Dynamic URLs unlock a faster, more efficient way to experiment with media. By shifting from static assets to flexible, on-demand transformations, teams can iterate quickly, reduce storage clutter, and deliver personalized experiences at scale. Cloudinary’s Dynamic URLs offer a powerful way to test, iterate, and optimize visual assets without creating multiple static versions.  ( 3 min )

    Why sharding is essential to fine-tuning LLMs
    This article was originally published on IBM Developer. Training and fine-tuning large language models (LLMs) is becoming a central requirement for modern AI applications. As these models grow in size—from billions to hundreds of billions of parameters—the demands on computational resources have increased dramatically. Fine-tuning such models on a single GPU is no longer realistic due to memory limitations and training inefficiencies. Sharding is the process of splitting a model’s data or components across multiple devices—such as GPUs or nodes—so that the training workload is distributed. By dividing the model’s parameters, gradients, and optimizer states into smaller “shards,” each device only needs to manage a fraction of the total, making it possible to train models that would not ot…  ( 4 min )

    Spell Checker-Predicting Correct Word by Editing two time-NLP
    We have already done checking spelling in one way, what I mean by that if spelling have one incorrect character then output will be correct that only. But now we are going to do it in two way meaning if we more than two character which is incorrect how we deal with that. One Edit Way: spell_checker('famili') Now we two character wrong then it return empty list. Two Edit Way: Whole code work the same, suggested_words = set(edit(word)) Calls the edit() function to get all 1-edit-away words (insert/delete/replace/swap). Converts the result into a set to: Remove duplicates Allow fast lookups and union operations for e1 in edit(word): Loops through each word that is 1 edit away. Each e1 is a candidate misspelling that might still be close to the correct word. suggested_words.update(edit(e1)) Calls edit() again to get all words that are 2 edits away (edit of an edit). Adds them into suggested_words using .update() (which merges sets). After this, suggested_words contains both: All 1-edit-away words All 2-edit-away words spell_check_edit_2("familea") Output: ['family', 'familiar', 'failed', 'families', 'famine']  ( 4 min )

    Understanding useCallback in React
    If you've been working with React function components, you might have heard about useCallback. But what exactly does it do and why is it useful? Let's break it down simply. The Challenge with Function Components function components re-run entirely on every re-render. This means that any functions you define inside your component are also recreated from scratch each time the component updates. While this behavior is usually fine, it can lead to performance issues, especially when you pass these functions down as props to child components. Enter useCallback: Memoizing Your Functions useCallback comes in handy. It's a React Hook that lets you memoize a function. In simple terms, it "remembers" your function. import React, { useCallback } from 'react'; function MyParentComponent() { const h…  ( 4 min )

    PHP Static Analysis Tools: Writing Bug-Free Code Before Execution
    “It worked on my machine” — a classic excuse we’ve all heard (or used). But what if your code never made it to a broken state in the first place? Static analysis is a silent hero in the PHP world, detecting errors, enforcing coding standards, and even directing architectural choices before your application receives a submission. One of the best things you can do is incorporate static analysis into your workflow, whether you're dealing with ancient codebases, developing Laravel apps, or expanding enterprise platforms. Let's explore the ways in which PHP static analysis tools, like PHPStan, Psalm, and PHP_CodeSniffer, can assist you in writing code that is safer, cleaner, and easier to maintain beforehand.

    Here Is Everyone Mark Zuckerberg Has Hired So Far for Meta's ‘Superintelligence' Team
    Here’s the scoop: Mark Zuckerberg just unveiled Meta Superintelligence Labs (MSL) in an internal memo, tapping Alexandr Wang (Scale AI’s CEO) as chief AI officer and former GitHub boss Nat Friedman as co-lab lead. Over the past few months Meta has splashed out $14.3 billion on Scale AI and gone on a full-on poaching spree, snagging top talent from OpenAI, Anthropic and Google to build its next-gen AI models. The memo drops a who’s-who list of hires—think folks behind GPT-4 variants (Trapit Bansal, Shuchao Bi, Huiwen Chang, Ji Lin, Hongyu Ren, Jiahui Yu, Shengjia Zhao), Anthropic inference guru Joel Pobar, DeepMind veterans Jack Rae and Pei Sun, plus Google Fellow Johan Schalkwyk—and hints at a serious sprint toward “superintelligence.”  ( 3 min )
    Longer antidepressant use linked to more severe, long-lasting withdrawal symptoms, study finds
    TL;DR A new Psychiatry Research study surveyed 310 long-term antidepressant users in the U.K. and found that the longer you pop those pills, the nastier—and stickier—the withdrawal. Less than six months of use saw mostly mild, short-lived symptoms (64% experienced some discomfort, only 7% severe). But after two years, a whopping 96% felt withdrawal, 25% had severe reactions, over 30% suffered for more than three months, and 79% couldn’t quit despite trying. Turns out most folks taper way too fast (or quit cold turkey), making matters worse. The paper argues for “hyperbolic tapering” (tiny, slowing dose cuts) and updated guidelines so patients aren’t blindsided by anxiety, “brain zaps,” dizziness and more. Bottom line: use antidepressants only as long as you need them—and plan your exit ramp from day one.  ( 3 min )

    Misusing OAuth 2.0 Client Credentials in Public Apps — A Security Breakdown
    Public-facing apps like React, Flutter, or plain JavaScript often make a critical OAuth mistake: they use the Client Credentials Grant to access protected APIs directly from the frontend. This breaks core OAuth security assumptions. In this post, I explain: What the Client Credentials Grant was designed for Why it’s dangerous to use in public apps Real-world risks like token leakage and backend impersonation What to use instead (like PKCE or backend proxies) The problem is more common than it should be — and it often goes unnoticed until something breaks. You can read the full breakdown here: https://blog.sentry.security/oauth-2-0-client-credentials-misuse-in-public-apps/ If you've encountered this or seen similar misuses, feel free to share or discuss below.  ( 3 min )
    🤖 Agentic AI: Why Everyone’s Talking About the Future of Autonomous Intelligence
    From AutoGPT to LangChain Agents, here’s why Agentic AI is shaping the future of how machines think, plan, and act on their own. Let’s be honest—AI is everywhere right now. We’ve gone from simple chatbots and automation tools to large language models (LLMs) like ChatGPT, Gemini, and Claude that can write code, generate essays, and even debate philosophy. But here's the twist: We're now entering a whole new phase of AI—something far more powerful and intelligent than anything we’ve seen before. It’s called Agentic AI. This isn’t just a buzzword. It’s a fundamental shift in how we design intelligent systems. Instead of passively waiting for commands, these new AI agents think ahead, take initiative, and work toward goals—on their own. If that sounds like sci-fi, hang tight. In this blog, we’…  ( 6 min )

    Advanced Tips for Building High-Performance Android Games
    1. Choose the Right Game Engine and Tools Early Selecting the right engine can define your game's technical limitations and possibilities. Unity and Unreal Engine are powerful, but not always necessary for simple 2D games. Lightweight engines like Godot or custom OpenGL-based frameworks may result in better performance on mid-range and low-end devices. Tip: Evaluate your game requirements before committing to a game engine. Don’t just follow trends—match the engine's capabilities to your gameplay goals. Assets (images, sounds, models) can make or break your game’s performance. Large uncompressed textures and high-bitrate audio can slow down loading times and bloat APK size. Use WebP for images instead of PNG. Compress audio using OGG Vorbis for a balance between quality and size. Lazy-lo…  ( 5 min )

    Part 10: Custom Hooks and Reusability – DRY Up Your React Logic
    Welcome to Part 10 of the React for Beginners series! As your app grows, you’ll find yourself repeating logic across components — like handling form inputs, toggling values, fetching data, etc. Wouldn’t it be great if you could extract and reuse that logic? You can — with custom hooks. A custom hook is a JavaScript function that: Starts with use Uses other hooks inside it (like useState, useEffect, etc.) Encapsulates reusable logic Think of it like a function component with no UI — just logic. Let’s say you want to toggle a boolean value (e.g., show/hide, like/unlike): /hooks/useToggle.js import { useState } from 'react'; function useToggle(initialValue = false) { const [value, setValue] = useState(initialValue); const toggle = () => setValue((v) => !v); return [value, toggle…  ( 4 min )

    Mixed-Source Computing:SPL Practices
    Background The sources and storage forms and types of data in an application are diverse, including not only the traditional relational databases, but also more data sources such as NoSQL databases, cloud storage, APIs, file systems, etc. Therefore, combining and analyzing data originating these different sources constitutes the problem of mixed data source computations. Logical data warehouses can facilitate mixed-source computations to some extent, because most of them are SQL-based and can access RDB data sources through table mapping. But it is difficult for them to access other types of data sources. Even with the help of complex data virtualization technology, they can only access some of those sources.

When prompted, specify the file name for the key. Press Enter to use the default path. You can add a passphrase to the key for extra security or leave it blank by pressing Enter. Your public SSH key is stored at: ~/.ssh/id_rsa.pub To view the public key, use: cat ~/.ssh/id_rsa.pub Copy the public key. Connect to your VPS manually using a password: ssh username@server_ip On the VPS, open or create the authorized_keys file: mkdir -p ~/.ssh nano ~/.ssh/authorized_keys Paste the public key you copied into the file. Save and exit the editor. Set the appropriate permissions for the file and directory: chmod 600 ~/.ssh/authorized_keys chmod 700 ~/.ssh On your macOS, test the SSH connection without a password: ssh username@server_ip To simplify SSH access, you can configure the ~/.ssh/config file: nano ~/.ssh/config Add the following: Host my-vps HostName server_ip User username IdentityFile ~/.ssh/id_rsa Now you can connect using: ssh my-vps By following these steps, you can securely and conveniently access your VPS without needing to enter a password every time.

Catalog and document Curated datasets Automate regular data workflows and pipelines The data engineer builds the system that delivers usable data to the data analyst, who querys and analyzes the data to gain business insights/reports/visualizations. Before a data engineer begins these questions must be answered: Which data should be analyzed? What is its value to the business or organization? Who owns the data? Where is it located? Is the data usable in its current state? What transformations are required? Who needs to see the data? After the data is curated and ready for consumption, how should it be presented?  ( 3 min )
    Django Architecture: What I Wish I Knew About Django’s Architecture Sooner "MVC vs MVT" Explained;
    Imagine building a house without a blueprint—walls might overlap, rooms could become inaccessible, and chaos would reign. Similarly, web apps need a clear structure to stay organized and maintainable. This is where architectural patterns like MVC and MVT come in! Brief context: Django, a popular Python framework, follows the Model-View-Template (MVT) pattern. Beginners often confuse MVT with the traditional Model-View-Controller (MVC). This article will clarify the differences and explain Django’s unique approach. What is MVC? MVC stands for Model-View-Controller, a software design pattern that separates an application into three main components: 1.Model: Handles data and business logic 2.View: Handles display and user interface 3.Controller: Handles user input and mediates between Model a…  ( 4 min )

    Coding Test - Snail wants to climb
    https://www.acmicpc.net/problem/2869 In the beginning, I thought it's so simple test because one while loop can solve it. But after I failure the test cases, I check one more time and they want "0.25" second of optimization. I found the math logic. each day, Snail climbs up and fell down, but other way, Snail is fell down and climb up. So there's this logic is available. n = days -fall * (n - 1) + climb * n >= max -fall * n + fall + climb * n >= max -fall * n + climb * n >= max - fall (climb-fall) * n >= max - fall n = (max - fall) / (climb - fall) and without loop, just one time of calculation is solving the problem!  ( 3 min )

    闭包(Closure) 是 JavaScript 中一个非常重要的概念,它是指 函数和声明该函数的词法环境(包含该函数的作用域链) 的组合。闭包使得函数能够记住并访问定义时的作用域,即使在函数外部调用它时,仍然可以访问这些变量。 闭包的特点: 1. 函数可以访问外部函数的变量。 2. 即使外部函数已经返回,内部函数仍然可以访问外部函数的局部变量。 3. 闭包可以创建私有变量,因为外部函数的局部变量对外部是不可见的,但内部函数能够访问和操作这些局部变量。 闭包的工作原理 当一个函数定义在另一个函数内部时,内部函数可以访问外部函数的变量。但是,通常在外部函数执行完后,其局部变量就会被销毁。闭包使得内部函数即使在外部函数执行完后,依然能够访问外部函数的局部变量。 示例 1:基本的闭包 function outer() { let counter = 0; // `counter` 是外部函数的局部变量 // 内部函数 function inner() { counter++; console.log(counter); } return inner; // 返回内部函数 } const myCounter = outer(); // 调用 outer 函数,并返回 inner 函数 myCounter(); // 输出 1 myCounter(); // 输出 2 myCounter(); // 输出 3 在上面的例子中: • outer 函数返回了 inner 函数。即使 outer 执行完毕,它的局部变量 counter 仍然存在于内存中,且 inner 函数仍然可以访问和修改它。 • inner 函数构成了一个闭包,绑定了 outer 的作用域。 示例 2:闭包与私有变量 闭包的一个常见用途是 模拟私有变量。由于外部无法直…  ( 3 min )

    Understanding the Singleton Pattern in JavaScript
    The Singleton pattern ensures that a class has only one instance and provides a global point of access to it. It's one of the classic Gang of Four (GoF) design patterns and is especially useful when managing shared resources, like configuration or database connections. It restricts the instantiation of a class to just one object. That object can be reused wherever needed, making it useful for things like: Configuration managers Database connections Logging services Global state management Basic Example in JavaScript: class Singleton { constructor() { if (Singleton.instance) { return Singleton.instance; } this.timestamp = Date.now(); // Sample property Singleton.instance = this; } getTimestamp() { return this.timestamp; } } // Usage co…  ( 4 min )

    How to Secure Nginx with SSL/TLS HTTPS Using Let’s Encrypt on Ubuntu
    Enabling HTTPS on your website is crucial for security, SEO, and user trust. Thankfully, Let’s Encrypt offers free SSL/TLS certificates that are easy to set up on an Nginx server. In this tutorial, we’ll walk through how to secure your Nginx server using Let’s Encrypt on Ubuntu. Before adding SSL, your website is likely still served over plain HTTP. Example: http://jadifullstack.id Make sure your system is up to date: sudo apt update sudo apt install certbot python3-certbot-nginx Certbot is the tool that will communicate with Let’s Encrypt and configure Nginx automatically. Run the following command to request and install your SSL certificate: sudo certbot --nginx -d jadifullstack.id If successful, you'll see a confirmation message: "Successfully received certificate" After a successful setup, your website will now be accessible via HTTPS. Example: https://jadifullstack.id Check that your browser shows a secure padlock and that HTTP requests are redirected to HTTPS. Let’s Encrypt certificates expire every 90 days. Certbot makes it easy to auto-renew them. You can verify the auto-renewal configuration with this command: sudo certbot renew --dry-run To schedule auto-renewal using cron, run: crontab -e Then add the following line to renew the certificate daily at noon: 0 12 * * * /usr/bin/certbot renew --quiet Now your Ubuntu VPS running Nginx is secured with HTTPS using a free SSL certificate from Let’s Encrypt. This simple setup improves trust, SEO ranking, and data protection. Always monitor your certificate expiration or use Certbot's auto-renewal to avoid disruptions. Want to take it further? Consider setting up a redirect from HTTP to HTTPS or enabling HTTP/2 for better performance!  ( 4 min )

    Fans slam The Alters after discovering evidence of undisclosed gen AI in images, text, and translation
    Fans of 11 Bit Studios’ new clone-survival game The Alters have spotted leftover AI prompts in on-screen flavor text and subtitles—including a Brazilian Portuguese line that literally says “The text translated to Brazilian Portuguese is…”—suggesting undisclosed use of large language models. Since January 2024, Valve’s Steam rules require devs to flag any AI-generated content, but The Alters’ store page makes no mention of it, sparking outraged Reddit and Steam threads. Not everyone’s losing their cool—some argue it’s just tiny sci-fi set dressing—but localization pros aren’t so forgiving. Experts say the botched PT-BR and Korean translations show careless AI use without proper editing, which feels like a slap to an international audience. 11 Bit Studios hasn’t publicly responded yet, even as the backlash grows.  ( 3 min )

The Hackclub Summer Project Unlike many web components out there, we are open source and free to use for developers to use! There are no premium blocks. As I write this blog post, I have made dozens of blocks with 10 categories, including; Marketplace, Dashboard Bills, Systems Monitoring, Banking, and many more! Furthermore I will add more various categories and blocks into the website! This probably include the blocks for Marketplace Seller Dashboard, Sales Dashboard, Pay-as-you-go Pricing block, Geography Chart, and more. I'm also interested to make a separate page to show components that might be useable for dashboard like various Cards UI, Buttons, toggle buttons and more!

    How Netflix, Stripe, and GitLab engineered Observability Culture
    Across organizations selling software, observability tools serve as the resource teams use to define value and assess product health. However, the truth is that observability tools, without observability culture, do very little to drive product quality. Observability culture is the collective mindset and shared practice of considering telemetry in every decision. But cultivating this culture can feel like a bit of a black box. After studying the observability practices of some of the industry’s top engineering organizations, I uncovered clear patterns that drive product stability at scale and why infusing proactive telemetry into a team’s DNA is critical for modern product reliability. Principles I’ve seen that drive observability culture can be boiled down to 3 key principles. Metrics tha…  ( 6 min )
    Playing with Stemming
    Let's start with this "text": {"path": "name", "query": "searches"} playground. Before we get into the textual analysis stemming topic, I want to share a different way of displaying search results in a playground. When playing with textual analysis, only a single document with a string field is needed. Rather than returning an empty array or an array containing only that one document from $search, I'd rather see literally 0 (false) or 1 (true) indicating whether the document matched the query or not. The $searchMeta stage performs the query the same as $search, but instead of returning an array of matching documents, it returns a single document of search result metadata. In this case, only the total count is included. No actual collection documents are returned from $searchMeta. [{ "$s…  ( 4 min )

    Write Unbreakable Code In Dart
    In software development, we spend an enormous amount of time writing defensive code. We check for null, handle exceptions with try-catch, and manage asynchronous operations with async/await. While these tools are essential, they often lead to code that is nested, verbose, and difficult to read. The core logic — the “happy path” — gets buried under layers of error handling. What if there was a way to write clean, linear code that describes the happy path, while all the messy details of null values, failures, and asynchronicity are handled automatically in the background? This is the promise of using Outcomes, a powerful concept from functional programming that you can use in Dart today to make your code dramatically more robust.

    One of the best BBC police dramas Line of Duty, that's "brutal", "thrilling" and "almost perfection" is now on Netflix
    Line of Duty has landed on Netflix, and if you’ve never dived into Jed Mercurio’s cult-classic cop drama, now’s your chance. Spanning six seasons since 2012, it follows Superintendent Ted Hastings (Adrian Dunbar) and anti-corruption team AC-12 (Vicky McClure, Martin Compston) as they sniff out bent coppers and organised crime. With a stellar 96% Rotten Tomatoes score (the first four seasons even hitting 100%), critics rave about its “brutal, thrilling” storytelling and “almost perfection” in plotting and character work. Beyond the nail-biting investigations, Line of Duty boasts an all-star guest lineup—Lennie James, Keeley Hawes, Thandiwe Newton and more—and has fuelled endless chatter over a potential Season 7 (though cast say it’s a long way off). Whether you’re in it for the meticulous writing, unforgettable villains or just top-tier police drama, head to Netflix (or catch up on BBC iPlayer) for a binge that’s still setting the gold standard.  ( 3 min )

    How coupled are your microservices?
    How Coupled Are Your Microservices? In this article, we address a crucial topic in software architecture: coupling and its main types in the context of microservices architecture. The motivation for this writing comes from direct experience with the negative impact of coupling on system design. In one project, delivered by a software house, we had to fully refactor it before going live due to excessive domain, pass-through, shared data, and content coupling. These interdependencies made the services fragile and undermined their autonomy, scalability, and maintainability. Understanding the different forms of coupling and their implications is essential for designing robust and scalable microservice systems. Before we explore the types of coupling, let’s understand how components communica…  ( 11 min )

    Scalability Trade-offs
    Ever wondered what happens when your side project goes viral overnight? You get thousands of users in an hour, and suddenly… your website crashes. It’s slow. Things break. And people leave. Why? Because your system wasn’t scalable. In this blog, I’ll break down scalability in a super simple way — no heavy jargon, just the real stuff you need to know if you're a developer, builder, or someone curious about how apps like Instagram or Amazon handle millions of users without falling apart. In simple terms: Scalability is the ability of a system to handle increased load — whether it’s more users, more data, or more traffic — without breaking, crashing, or slowing down. So when we say “this app scales well,” we mean: “It still works smoothly, even if a lot more people start using it.” Here’s …  ( 5 min )

    🎮 Game On! Understanding `requestAnimationFrame` for Smooth Animations in JavaScript Games
    Ever wondered how browser games move objects smoothly across the screen, like a character jumping or a ball bouncing? The secret is requestAnimationFrame, a built-in browser method designed for smooth, efficient animations. In this article, we’ll explore what requestAnimationFrame does, why it’s awesome for games, and how to use it in a simple game loop. requestAnimationFrame? requestAnimationFrame is a JavaScript method that tells the browser: “Run this function before the next repaint.” This makes it perfect for smooth animations because: It's synced with the screen’s refresh rate (usually 60 FPS). It pauses automatically when the tab isn't visible (saving power). It’s more efficient than using setInterval() or setTimeout() for game loops. In games, we often update the position of thin…  ( 4 min )

    Jesse Eisenberg asked for a copy of his Modern Family episode with his scenes cut out
    Here’s the TL;DR: Jesse Eisenberg—an admitted Modern Family superfan—actually guest-starred as Asher in a 2014 episode, but was so shy about his own scenes that he asked producers to send him a version with his bits chopped out so he could still watch the show. Jesse Tyler Ferguson spilled the story on his Dinner’s On Me podcast, and Alexander Skarsgård later added that at The Hummingbird Project premiere, Eisenberg sprinted the red carpet, bailed for two hours, then snuck back in. Turns out this isn’t a one-off. Eisenberg’s famously sensitive about his on-screen work—he’s said his turn as Lex Luthor in Batman v Superman wounded his career—but bounced back by writing, directing and starring in A Real Pain, earning Oscar nods for Best Original Screenplay (and a Supporting Actor win for Kieran Culkin).

    Linux from the developer's perspective. Part 2 - Compilation and linking
    This blog is part of a series How does a C program get compiled? For C-like languages, compilation involves four steps: Preprocessing, compile-time metaprogramming Compilation itself, translation of the source code to assembly Assembling, turning assembly into machine code in an object file Linking, turning the object file into an executable or a library Of course, all these categories, except for linking, are to some degree arbitrary. Preprocessing is an anomaly, a language within a language, a crutch - it exposes the limited expressive power of the base language. Compilation is to a degree arbitrary, because you can embed assembly code into C code, which doesn't require compilation. Assembly is not actually assembly - it's Gnu Assembly, the universal assembly. Originally, the assembly la…  ( 9 min )

    Apple Research just unearthed a forgotten AI technique and is using it to generate images
    TL;DR: Apple dusted off an old AI trick—Normalizing Flows—and spiced it up with Transformers to create two new image generators: TarFlow and STARFlow. Unlike diffusion or token-based autoregressive models, flows learn a reversible “noise ↔ image” mapping that gives exact likelihoods. TarFlow chops images into patches and predicts pixel values in sequence (no token compression!), while STARFlow works in a smaller latent space before upsampling to high-res, and even plugs in lightweight language models for text prompts. The big sell? These flow-based models could run on your device, offering crisp detail and probability-aware outputs without constant cloud crunching. It’s a different path than OpenAI’s GPT-4o, which treats images like giant token streams in the cloud—flexible but heavy and potentially slower—whereas Apple’s approach is built for speed and efficiency in our pockets.  ( 3 min )

    How Bolt.new Helped Me Go From Beginner to Builder in the World's Largest Hackathon
    How Bolt.new Helped Me Go From Beginner to Builder in the World's Largest Hackathon I first discovered Bolt.new during the winter — and back then, I barely knew how to build anything. But I immediately got inspired by the way Bolt built websites so cleanly, with no errors. I had used other services before, but they often had bugs or broken features. Bolt felt different — solid, fast, and reliable. That moment hooked me. Since then, I kept building. I created more and more projects with Bolt, learning as I went. Then I found out about the World’s Largest Hackathon, and I thought — maybe I should join? So I did. I built a full project called OpenSource Hub in just a few days. It’s a platform where people can publish and share open-source websites, apps, and games — kind of like GitHub, but much simpler and visual. Bolt.new was a huge help during this process. For example, when I was setting up Firebase for backend and database, Bolt guided me step-by-step to run specific commands and deploy it correctly. Thanks to Bolt, I learned so much. Now I feel confident building full-stack projects, using TypeScript, Vue, APIs, AI (like Gemini 2.5 Flash), and more. And I’m really proud of what I made — and how far I’ve come. Thank you, Bolt.new.

    How to Install Jan-Nano-128k: The AI Model with 128K Context Window for Deep Research
    If you've been exploring compact language models for research, chances are you've already come across the impressive Jan-Nano, a lightweight, high-performance model that recently gained popularity for its speed and versatility. But one of its key limitations was its relatively short context window, which often forced researchers and developers to chunk or truncate large documents. Since long context window is a very important factor in areas like deep research, Menlo Research team just launched Jan-Nano-128k, a game-changing upgrade that natively supports an astonishing 128,000-token context window. It is built from the ground up to handle long-form content without the performance degradation seen in traditional context extension methods like YaRN. If you're analyzing full-length research …  ( 8 min )

    🔍 Docker Hub: Digging Deeper into the Heart of Container Sharing
    If you're working with Docker, chances are you’ve already heard of Docker Hub. But what is it, really? Is it just a place to download images? Or is there more going on under the surface? Let’s dig deeper—and don’t worry, we’ll keep things light, fun, and super friendly so you can enjoy every bit of this journey. 🎉 Docker Hub is like the App Store or Google Play for container images. It’s an online registry where: You can find ready-to-use container images (like Node.js, MongoDB, Nginx, and more). You can store and share your own container images. You can automate builds and even scan for vulnerabilities. In short: It’s the home base for your Docker images. Public repos: Anyone can pull (download) your image. Great for open-source projects. Private repos: Only you (or your team) can access…  ( 4 min )

    Bayesian Networks for Production ML: Architecture, Observability, and Scalable Inference 1. Introduction Last quarter, a critical anomaly detection system in our fraud prevention pipeline experienced a 15% increase in false positives following a model update. Root cause analysis revealed the new model, while improving overall precision, exhibited unexpected conditional dependencies not captured during offline evaluation. This highlighted a critical gap: our existing monitoring lacked the ability to track and validate the reasoning behind model predictions, not just the predictions themselves. This incident underscored the need for integrating Bayesian Networks (BNs) not as standalone models, but as a crucial component within our broader MLOps infrastructure for explainability,…  ( 7 min )

    Using the Fetch API
    Fetch API provides a JavaScript interface for making HTTP requests and processing the responses. Fetch is the modern replacement for XMLHttpRequest: unlike XMLHttpRequest, which uses callbacks, Fetch is promise-based and is integrated with features of the modern web such as service workers and Cross-Origin Resource Sharing (CORS). With the Fetch API, you make a request by calling fetch(), which is available as a global function in both window and worker contexts. You pass it a Request object or a string containing the URL to fetch, along with an optional argument to configure the request. The fetch() function returns a Promise which is fulfilled with a Response object representing the server's response. You can then check the request status and extract the body of the response in various formats, including text and JSON, by calling the appropriate method on the response. Here's a minimal function that uses fetch() to retrieve some JSON data from a server: js https://example.org/products.json"; Response status: ${response.status}); const json = await response.json(); console.log(json); } catch (error) { The fetch() function will reject the promise on some errors, but not if the server responds with an error status like 404: so we also check the response status and throw if it is not OK. Otherwise, we fetch the response body content as JSON by calling the json() method of Response, and log one of its values. Note that like fetch() itself, json() is asynchronous, as are all the other methods to access the response body content. In the rest of this page we'll look in more detail at the different stages of this process. Making a request a definition of the resource to fetch. This can be any one of: Setting the method js https://example.org/post", { Setting a body To set a request body, pass it as the body option: js https://example.org/post", { method: "POST", body: JSON.stringify({ username: "example" }), // … });  ( 4 min )
    Small Projects That Taught Me Big Lessons in Web Development
    When you're starting out in web development, everyone says “build projects.” But no one really tells you that small projects can teach you big things. Sometimes more than the tutorials or courses you grind through. Here are a few mini-projects I built, what went wrong (or right, ha-ha), and the lessons that stuck with me way beyond the code. 1. The To-Do App (Yes, I Know) DOM manipulation gets messy fast without structure State management isn’t just a “React problem” UX matters more than you think — if deleting a task isn’t obvious, no one cares that it works 2. A Simple Portfolio Website Responsive design isn’t optional “Looks good on my screen” ≠ good enough Using rem/em units and flexbox/grid properly saves headaches later 3. A Weather App Using an API API keys, rate limits, and error handling are real things Skeleton loading states are underrated My point is, you don’t need to build the next Uber clone to become a better developer. Build small. Break stuff. Fix it. Repeat. Baby steps are super important as well. Let's keep growing together!  ( 3 min )

    DAY 15-CSS FLEX
    Hello all......today I am going to talk about the master of content alignment in CSS which is Flex. If you ask any web developer today what feature do they use for aligning content, all of them will tell about Display->Flex. In short this is a boon for all developers...it does not have the confusion which exists in absolute and relative positioning as to whether we need to specify top or bottom etc etc. display->flex and set the flex-direction to either row ,row-reverse ,column or column-reverse. two components in flexbox, parent and child. The element which has the display property set as flex is the parent component and the elements inside the parent is the child component. Every parent element in flex gets access to the following properties: 1.Flex-Direction: The flex-direction property specifies the display-direction of flex items in the flex container. The flex-direction property can have one of the following values, depending on which the flex items are aligned on the main-axis. The default one is row. row 2.Justify-Content:The justify-content property is used to align the flex items when they do not use all available space on the main-axis (horizontally). The justify-content property can have one of the following values: center 3.Flex-Wrap:The flex-wrap property specifies whether the flex items should wrap or not, if there is not enough room for them on one flex line. The flex-wrap property can have one of the following values: nowrap 4.Align-Items:The align-items property is used to align the flex items when they do not use all available space on the cross-axis (vertically). The align-items property can have one of the following values: center I will continue about this in the next post....see you all there..  ( 3 min )

    MVT vs MVC Architecture
    Understanding Web Development Patterns Web application development relies heavily on architectural patterns. Two prominent patterns are MVC (Model-View-Controller) and MVT (Model-View-Template). While MVC is the traditional and widely adopted pattern, MVT is Django's interpretation that offers unique advantages for Python web development. Let's explore both patterns, their core functions and strength MVC (Model-View-Controller) is a software architectural pattern that separates an application into three interconnected components.

    Django MVT vs MVC Explained Simply for Beginners
    I’ve been learning Django recently, and I kept seeing two things: MVC and MVT. At first, they looked like the same thing — just a different name — but the more I dug into Django’s docs and tutorials, the more confused I got. 😅 So if you're just getting started with Django (like me) and scratching your head over these two acronyms, don't worry — you’re not alone. Let me walk you through how I finally made sense of it all. When I first saw MVT, I thought: “Wait, isn't this just MVC with a different hat on?” But the thing is — Django doesn’t fully follow MVC. It uses a pattern called Model-View-Template (MVT), and while it looks similar to MVC, there are some tricky naming differences that can throw you off. To really get it, I had to break things down in a way even my little cousin could un…  ( 5 min )
    From Bugs to Brilliance, Leveling Up JavaScript with TypeScript
    Why should we look into TypeScript? Imagine JavaScript injected with steroids, that’s TypeScript. While JavaScript offers flexibility and freedom, it also leaves plenty of room for bugs and silent failures. TypeScript, on the other hand, brings structure and type safety, which becomes especially valuable when working in teams. In this blog, we’ll explore why more developers are making the switch from JavaScript to TypeScript and why you might want to consider it too. TypeScript is a statically typed superset of JavaScript created by Microsoft It adds optional type annotations, interfaces, and modern JavaScript features, then compiles (transpiles) down to plain JavaScript that runs in any browser or JavaScript environment.

While JavaScript engines have improved dramatically, complex image operations like filtering, format conversion, and real-time manipulation still struggle with large images or demanding operations. WebAssembly (WASM) changes this paradigm completely. WebAssembly enables near-native performance for image processing directly in the browser, opening possibilities that were previously only available on the server. This comprehensive guide explores how to leverage WASM for high-performance client-side image processing, from basic setup to advanced real-time applications. The performance difference between JavaScript and WebAssembly for image processing is dramatic: // Performance comparison: Jav…  ( 11 min )
    This React Alternative Turned out Better than I Thought
    Introduction I was always striving for something better, first I was making my own little tools working with JQuery, then I started learning more about VanilaJS, after all I found React. It was a Heaven that day, but learning deeply was really something incredible difficult and felt like hell. Now I'm very used to React, I don't even think about how things work anymore, I'm just building - which is great! Unless you want to strive for more. While learning React I was trying out how I could build application with different architectures. The thing I figured out is that everything is possible, but you need hooks :) This means you can't use your tools you've been developing and polishing for years in another frameworks or just in VanilaJS. While figuring out architecture patterns and how I…  ( 5 min )
    Replyke vs Disqus: Complete Guide to Website Commenting Systems in 2025
    The battle for user engagement on websites has never been more critical. While social media platforms capture attention, website commenting systems remain the backbone of community building and content discussion. In this article, I will compare two distinct approaches: Disqus, the established player with millions of installations, and Replyke, the developer-focused newcomer promising modern API-first architecture with zero ads. Comment sections drive 60% more engagement than static content alone, according to recent studies. Yet the landscape has dramatically shifted. Users expect Instagram-style threading, real-time notifications, and seamless mobile experiences—features that traditional commenting systems struggle to provide. The fundamental question facing developers today: Should you …  ( 7 min )
    Golang Context Package: A Guide to One of the Most Used Packages in Go
    So, you're writing some Go code and you keep seeing context.Context pop up everywhere, right? Especially if you're building network servers or anything that juggles multiple tasks at once. This package was added way back in Go version 1.7, and it's super important for writing good, solid code. But what does it actually do? And why should you care? Let's dive in and figure it out! The "Why": The Problem Context Solves The user cancels the request: The user just closes their browser tab. Your server, not knowing this, carries on with the database query and the API call, wasting CPU, memory, and network resources on a result that no one is ever going to see. An operation is too slow: The external API is taking forever to respond. You don't want your server to hang forever, tying up resources.…  ( 7 min )
    HTML Form Inspector: inspect and debug your forms online
    HTML forms are notoriously hard to get right. They require a lot of boilerplate HTML and even small mistakes can lead to frustrating user experiences like not being able to click a label to toggle a checkbox. Because forms are so verbose, it can also be hard to discover issues in them just by looking at the code. For example, how long does it take you to spot the problem in this form?

    AI Won’t Replace Quality Engineers — It Will Empower Us
    Automation didn’t replace testers — it made them more valuable. AI will do the same. I’ve been reflecting lately on how much the world of Quality Engineering is changing — and honestly, I’m excited. At first, I had second thoughts. Like many in tech, I wondered: Will AI replace QAs and QEs? But the more I explored, the clearer it became — AI is not a rival. It’s a powerful ally. Remember when automation testing first entered the scene? The buzz was intense. People thought manual testers would disappear. But what really happened? Automation simply took care of the repetitive, low-value tasks. It freed up testers to focus on exploratory testing, UX, and strategy. It didn’t replace us — it empowered us. AI is doing the same — just at a whole new level. We’ve started exploring using AI in so many exciting ways: Eventually, QEs will not be bogged down with boilerplate automation scripts. Instead, we get to do what we do best — think critically about quality. This shift initially scared me — but after exploring, it energizes me. I’m genuinely excited by all the possibilities AI brings to the table for Quality Engineers. 🚀 AI is becoming the always-on assistant that lets us focus on: The future of QE isn’t “AI vs Human”. It’s AI + Human — a collaboration where we focus on strategy, and AI takes care of the heavy lifting. As QEs, we’re not being replaced — we’re being elevated. Let’s embrace AI. Let’s learn it, guide it, and use it to build better, faster, and smarter. I’m already seeing it transform my work — and I can’t wait to see what’s next. ✍️ Are you using AI in your QA workflows? I’d love to hear what tools you’re trying or where you’re seeing the most impact! Let’s share and learn together. 👇  ( 4 min )

    AWS Cost Optimization- Identify Stale Resources using Lambda Function.
    what is lambda function in AWS services? Problem Statement: When a user creates an EC2 instance, an associated EBS volume is also created. The user typically takes snapshots of this volume for backup purposes. However, after a few months, the user deletes the EC2 instance and the volume but forgets to delete the associated snapshot. As a result, the unused snapshots continue to incur storage costs, leading to unnecessary and increasing expenses over time. As DevOps engineer, It is essential to address this by implementing cost optimization strategies to identify and clean up unused snapshots to reduce AWS costs. Solution: To solve this problem statement we use Lambda funtion fetches all EBS snapshots owned by the same account and also retrieves a list of active EC2 instances. For each snap…  ( 5 min )

    How API architects can prepare for the Agentic AI shift?
    Agentic AI changes how APIs are consumed, from human-triggered, one-time calls to autonomous, multi-step interactions. This demands a fundamental shift in how APIs are designed, documented, secured, and governed. API architects play a critical role in ensuring that enterprise systems are ready to support these intelligent agents. Here’s how to prepare: Design for machine-to-machine consumption: Agents don’t read docs like humans. APIs must be self-descriptive, machine-readable, and semantically clear. Use standardised schemas (like OpenAPI), meaningful parameter names, and well-defined response structures to make endpoints agent-friendly. Embrace the Model Context Protocol (MCP): MCP is emerging as the standard to make APIs "agent-ready" by exposing metadata like usage context, auth requir…  ( 3 min )
    Flintable - Introducing Flint
    Flint is a Git-integrated code formatter that lets each developer work in their preferred style locally while maintaining a consistent style remotely. By automatically applying “local” and “remote” formatting passes during pull and push operations, Flint prevents formatting noise in commits and code reviews.             To get started quickly, head over to this link.     As code artisans, we each have our own tastes: brace styles, indent sizes, maximum line lengths… Yet when collaborating, these personal choices can diverge, clutter pull requests, and slow down code reviews. Existing tools like Prettier enforce strict, uniform rules that are convenient but inflexible when you want to keep a personal touch.     Flint bridges that gap: you code in your local style, then Flint automaticaly re…  ( 4 min )
    Parse nice int from char problem

    ⚡ React Performance: How to Optimize Your Components for Lightning Speed
    Hey DEV! 👋 React is awesome, but slow components hurt UX. Here are quick tips to speed up your React apps. Let’s go! 🚀 ✅ 1) Avoid Unnecessary Re-renders with React.memo React re-renders components whenever their props or state change. However, sometimes re-rendering isn’t needed if props haven’t changed. const MyComponent = React.memo(function MyComponent({ data }) { console.log('Rendered'); return {data} ; }); React.memo memoizes the component and prevents re-renders when props are the same, improving performance. ✅ 2) Use useCallback to Memoize Functions Functions defined inside components are recreated on every render, causing child components to re-render if these functions are passed as props. const handleClick = useCallback(() => { console.log('Clicked!'); }, []); …  ( 4 min )
    I made a web app to visualize my next hair color
    I am a young software developer who enjoys coloring my hair -- green, blue, pink, purple -- I tried all of them! However, I only get one color each time (e.g., coloring the entire head to red/blue,etc. ). I wish to try some creative colors, but based on my previous experience, how my hair actually looks is always different than what I want, so I want to make software to visualize it under different lighting conditions and environments. I call it Tress Assistant, and this is a pure-frontend web application. Features: Blend your natural hair color with one or more artificial colors. I designed a mathematical formula for it. Preview different hairstyles. Dynamic lighting system, which is based on current date and time and your location Rotate models Technologies Used: React Three.js Material UI Tailwind Zustand Vite You can try it by visiting https://app.tressassistant.net/ or visit my GitHub repo at https://github.com/TressAssistant/Tress-Assistant-Web To be frank, the 3D part is not perfect, as I'm using models as hair, which looks not realistic.

    Understanding Content Security Policy (CSP) in JavaScript Apps
    Hey folks, let’s dive into Content Security Policy (CSP) — a powerful yet often misunderstood tool that helps you lock down where your app can load resources from, protecting against XSS, click‑jacking, and more. CSP is a browser‐enforced set of rules—sent via HTTP headers (or tags)—that defines which sources your app can load scripts, stylesheets, images, frames, and other resources from For example: Content-Security-Policy: default-src 'self'; img-src 'self' example.com; This means: By default, only load assets from the same origin example.com Block XSS attacks – Restrict script sources so injected code can’t run Block click‑jacking – Prevent framing via frame-ancestors Enforce HTTPS – Use upgrade-insecure-requests to force secure loads Boost trust – Shows users you care about security default-src – default fallback for everything script-src, style-src, img-src, connect-src, etc. – control specific asset types object-src 'none' – block Flash & plugins frame-ancestors 'none' – prevent embedding (stronger than X-Frame-Options) 👉 Want to see the full breakdown with real‑world examples, error cases, and extra tips?

    Key Steps in the Master Data Governance Process
    The Master Data Governance Process is vital for ensuring that enterprise data remains accurate, consistent, and compliant. It begins with identifying the core data domains that need governance—such as customers, products, vendors, and assets. The next step involves establishing clear ownership by assigning data stewards and defining roles across departments. Policies are then created to standardize data entry, validation, and lifecycle management. A feedback mechanism ensures continuous improvement and resolution of data issues. This structured approach not only enhances operational efficiency but also reduces compliance risks and improves trust in business intelligence outcomes.  ( 3 min )
    My Learning Today – JavaScript Promises, Async/Await, Fetch, and Axios
    Today, I learned some very useful things in JavaScript that help to handle asynchronous tasks. These topics were Promise, async/await, fetch, and axios. A Promise is used in JavaScript to handle tasks that take some time, like getting data from a server. It has three states: Pending – waiting for the result Resolved – task completed successfully Rejected – task failed Example: let promise = new Promise((resolve, reject) => { let success = true; if (success) { resolve("Data received!"); } else { reject("Something went wrong!"); } }); async and await make it easier to work with Promises. Instead of .then() and .catch(), we can write code like normal steps. Example: async function getData() { let result = await fetch("https://api.example.com/data"); let data = await result.json(); console.log(data); } getData(); fetch() is used to get data from a web API. It returns a Promise. Example: fetch("https://api.example.com/data") .then(response => response.json()) .then(data => console.log(data)) .catch(error => console.log(error)); Axios is another way to fetch data from APIs. It is easier and has more features than fetch. Example: axios.get("https://api.example.com/data") .then(response => console.log(response.data)) .catch(error => console.log(error));  ( 3 min )

    Implementing Domain Driven Design - Entities
    We continue our series in the chapter 5 about Entities 😁 A. The problem Here is the problem, our entities do not reflect the importance of Instead of designing domain concepts with rich behaviors, we might think primarily about the attributes (columns) and associations (foreign keys) of the data. Doing so reflects the data model into object counterparts, which leads to almost every concept in our “domain model” being coded as an Entity abounding with getter and setter methods. here is the problem, we have entities we only getters and setters and no domain logic! B. What is a true Entity We design a domain concept as an Entity when we care about its individuality, when distinguishing it from all other objects in a system is a mandatory constraint.

    Understanding Space and Time Complexity in Software Development
    In the world of software development, writing code that works is only half the battle. The real challenge lies in writing code that performs efficiently and scales well. This is where understanding space and time complexity becomes essential. This article aims to explain the core ideas behind these concepts, what they are, why they matter, and how to reason about them using Big O notation. Runtime refers to the actual time it takes for a program or algorithm to complete a task. However, when analyzing algorithms, we are more interested in time complexity, which expresses how the runtime grows in relation to the size of the input. Time complexity helps us reason about performance regardless of specific hardware or system load. It tells us how well an algorithm will scale and is typically ex…  ( 8 min )
    Kubernetes Day 2: Pods, Deployments, ReplicaSets, & DaemonSets: Your App's Superheroes\! 🦸‍♂️🦸‍♀️

    Immersive Ticket Booking in WebXR with Three.js – View & Hear Before You Book!
    For the past few days, I’ve been working on something that merges my love for immersive tech and practical real-world use: a WebXR ticket booking experience. You can try the live demo here: Live link Here's a quick screen recording of the full experience: Video Link When you book tickets online — whether for a concert, movie, or sports event — you're usually shown a 2D seat map or a price category list. But you never truly know: What’s the view really like from that seat? How close are you to the stage? What will the sound feel like? So I thought: That’s how this idea started — a fully immersive, VR-capable ticket booking interface where you can: See the seat layout in 3D Select any seat interactively Instantly preview the view from that seat Hear directional sound from the stage Tech I Used Three.js for 3D rendering WebXR for the VR experience (works in browser-supported headsets) GLB models for seats and stage layout Raycasting for selecting seats THREE.PositionalAudio for spatial sound Some plain JavaScript and a simple simulated booking flow 🖱️ How the Interaction Works When you select a seat: The camera smoothly transitions to that seat position. A positional audio layer starts playing as if you're in the environment. You get a real sense of what it’s like sitting there. The view is exactly from that seat’s coordinates — not just a general overview. This works well especially for large venues where every row feels different. 🔊 Sound Preview I added 3D positional audio using Three.js’s PositionalAudio. Depending on your seat's location, the sound gets softer, louder, or shifts left/right — giving you a preview of the acoustic experience.  ( 3 min )

    What is Fetch? Fetch is a built-in JavaScript function used to make HTTP requests. It returns a Promise and is commonly used to interact with APIs. It requires manual response parsing using .json() and handles asynchronous operations with either .then() chaining or async/await. Example with Fetch using .then() function getWeather() { const city = document.getElementById('input-value').value; const result = document.getElementById('result'); const apiKey = "YOUR_API_KEY_HERE"; const url = `http://api.openweathermap.org/data/2.5/weather?q=${city}&appid=${apiKey}&units=metric`; fetch(url) .then((response) => { return response.json(); }) .then((data) => { console.log(data); result.innerHTML = `Temperature: ${data.…  ( 4 min )
    ✅ 10 React Best Practices Every Developer Should Know in 2025
    Hey DEV community! 👋 React is evolving fast, and staying up-to-date with best practices is key to writing clean, efficient, and maintainable code. ✅ 1) Keep Components Small and Focused A component should ideally do one thing well. Large, “God components” are hard to test and maintain. Split big components into smaller, reusable ones. ✅ 2) Use Functional Components and Hooks Class components are outdated for most use cases. Embrace functional components with hooks for state, side effects, and more — they’re simpler and less verbose. function Counter() { const [count, setCount] = useState(0); return setCount(count + 1)}>Count: {count}; } ✅ 3) Destructure Props and State Avoid using props.someValue everywhere.

    How to Raise SaaS Prices Without Losing Your Users
    Let’s be honest—raising prices is awkward. You worry about losing customers. You worry about breaking something that already works. So you push it off. But the truth is: keeping your pricing frozen while your product evolves can quietly hold back your growth. If your SaaS product has added real value—new features, better reliability, faster support—then your pricing deserves a second look. Many founders treat pricing like a "set it and forget it" system, but in reality, it's one of the most powerful levers in your business. This post is for: Devs working on bootstrapped or early-stage SaaS Technical founders wondering if they’re undercharging Anyone who’s improved their product, but kept prices the same Here’s how to tell if it’s time to update your pricing—and how to do it without losing trust or customers. When Is It Time to Revisit Your SaaS Pricing? You’ve Added Serious Value New features? Better performance? Smoother UX? Fewer bugs? If your product is better than it was 6–12 months ago, your pricing should evolve with it. Your Support & Service Have Leveled Up Customers Say It’s “Cheap” Your Early Pricing Was Temporary You’re Attracting the Wrong Customers If your product has matured, your pricing needs to reflect that. Otherwise, you risk signaling that your value hasn't kept up. That can hurt trust, not just profit. You don’t need to double your price. But you do need a strategy. Here’s what works, especially in SaaS: Reward Existing Customers Use Data (and Feedback) Change Tiers, Not Just Numbers Frame the Change Around Value Thread This Into Product-Led Growth Build features → Raise value → Raise prices → Reinvest → Repeat The loop only works if your pricing reflects your product Pricing is part of product-market fit What’s your approach to pricing?

    Rate Limiting: The Unsung Hero of Web Security
    Web applications today are exposed to a wide range of automated threats — bots trying to brute-force passwords, scrapers crawling your data, or malicious actors hammering your endpoints with requests. You may have a firewall. You may have authentication. But if you're not using rate limiting, you're leaving the door wide open. Rate limiting is the process of restricting how many times a client can make a request to your server in a given time window. It’s one of the most effective — and often overlooked — defenses in modern web security. You can apply rate limiting to: IP addresses Sessions or tokens Specific URLs or endpoints User agents or header patterns It doesn’t just slow things down — it stops abuse at the source. Without rate limiting, even the most secure apps are vulnerable to: A…  ( 4 min )

    AI-Native Plugging in a Model
    How SeaOS Redefines On-Chain Intelligence The Legacy Approach: AI as an Add-On, Not Infrastructure A pre-trained AI model is hosted off-chain. A smart contract calls the model via an API or oracle. The AI outputs are fed back into the chain for settlement or storage. While functional, this model introduces significant limitations: Smart contracts remain static. They cannot learn, adapt, or evolve over time. AI logic remains off-chain. The model lives outside the decentralized network, with limited transparency or coordination. Semantic gaps persist. The integration is superficial—contracts and models speak different languages, with minimal real-time feedback or shared state. The result? Most so-called AI applications are merely "model + chain" hybrids, not truly AI-native systems. SeaOS’s …  ( 5 min )
    Understanding the Reflect API in Depth
    Understanding the Reflect API in Depth Introduction The Reflect API is a collection of static methods introduced in ECMAScript 2015 (ES6) that provides a meta-programming interface for JavaScript. It enables developers to manipulate objects at a lower level with a focus on enhancing versatility and encapsulation. The Reflect API is pivotal for advanced development practices, serving not only as a tool for managing object behavior but also as an enabler of sophisticated programming paradigms such as proxies and decorators. Before ES6, JavaScript heavily relied on traditional object manipulation methods, often leading to code that was difficult to maintain and optimize. Methods like Object.create(), Object.defineProperty(), and others existed but did not provide a uniform way to…  ( 6 min )
    How to calibrate a temperature sensor?
    Calibrating a temperature sensor involves comparing its readings to a known accurate reference and adjusting for any error. Here's how to do it step by step: 1. Understand the Sensor Type Analog (e.g., LM35, TMP36) Digital (e.g., DS18B20, DHT11/22, SHT31) Thermistors (resistance-based) Calibration methods vary depending on the sensor type. 2. Gather Required Tools 3. Perform Multi-Point Calibration a. Prepare Calibration Points Ice water (~0°C) Room temperature (~20–25°C) Warm water (~50–60°C) or boiling water (~100°C) b. Measure Each Point Place sensor and reference in the same environment Let them stabilize for a few minutes Record both sensor reading and actual temperature 4. Calculate Error or Offset For digital sensors: cpp float offset = reference_temp - sensor_reading; float corrected = sensor_reading + offset; For analog sensors or thermistors: Create a calibration curve (e.g., linear or polynomial) Use regression or map equations to adjust readings in code 5. Update Your Code Example (Arduino): cpp float rawTemp = readSensor(); // Your sensor reading function float offset = -1.5; // Calibrated offset float correctedTemp = rawTemp + offset; Or for scaling (linear correction): cpp float scale = 1.02; float offset = -1.1; float correctedTemp = (rawTemp * scale) + offset; 6.

Suddenly, your clean navigation code turns into a maze of string-based identifiers, scattered NavigationLink destinations, and a growing sense of dread every time someone mentions "deep linking." What if I told you there's a way to handle all of this with type-safe enums that scale beautifully with your app's complexity? enum AppDestination: Hashable { case home c…  ( 4 min )

    Snapdom: a modern and faster alternative to html2canvas
    In less than two months, Snapdom reached 2,120+ stars, with 7 contributors and a growing user base. But the goal has been clear since day one: Build a modern, accurate and fast replacement for html2canvas. html2canvas was a milestone. I love it. It brought DOM-to-image to mainstream frontend. But time has passed, and the web platform has evolved: higher DPI screens, complex shadows, pseudo-elements with ::before { content: url(...) }, imported icon fonts, variables inside gradients, shadow DOM, web components, and more. Many of those features don’t render correctly in html2canvas. Snapdom aims to fix that with a new approach. Snapdom captures how a DOM looks. While tools like html2canvas attempt to reproduce the layout procedurally using canvas drawing commands, Snapdom takes a different …  ( 4 min )
    Symfony Command Injection: Risks & Secure Coding
    🚨 What Is Command Injection in Symfony? Command injection (aka OS command injection) happens when unsanitized user inputs are concatenated into system commands—letting attackers run arbitrary commands on your server. In Symfony, it often occurs when developers use functions like shell_exec(), exec(), or insecure template rendering without input validation. Imagine a Symfony controller that executes arbitrary system commands based on user input: // src/Controller/SystemController.php public function ping(Request $req): Response { $ip = $req->query->get('ip'); $output = shell_exec("ping -c 4 $ip"); return new Response(" $output "); } An attacker could inject something like: 127.0.0.1; cat /etc/passwd This executes cat /etc/passwd after ping, exposing sensitive file…  ( 4 min )

    The Internet’s Full of Trash Info, So I Made Nexix. You’re Welcome 💅
    You ever search something online and end up reading a novel about someone’s traumatic backstory with JavaScript just to find the answer in paragraph 47? Same. So I said screw that — and I built my own thing. Introducing: Nexix. It’s like ChatGPT, Google, and Wikipedia had a baby… but then that baby said “nah, I’m built different.” Nexix is an AI-powered platform that answers your questions fast, clean, and with no fluff. No SEO clickbait. No 5-minute intros. Just facts, clarity, and boom—you’re smarter. And yes, it works on your phone. No, you don’t need to download anything. And YES, it’s free. Because your brain deserves better than fighting through ad-ridden blog jungles. I was tired of “how to center a div” turning into a TED Talk about CSS history. I wanted to learn fast, not read war and peace every time I had a question. And most AI tools? Either too slow, too generic, or trying too hard to sound like Shakespeare with a laptop. So I made Nexix: ✨ Beautiful glassmorphic UI (dark theme, blue accents, chef’s kiss) 🧠 Answers generated instantly by AI (via Groq, so it’s F A S T) Students tired of searching the same crap over and over Indie devs like me who hate wasting time Curious minds who want answers, not clickbait People who value their time over someone’s recipe blog from 2014 👉 [https://nexix.netlify.app] Just search something. Anything. You'll either learn something, or get addicted to how fast it is. Either way, W. Drop 'em. Roast it. Praise it. Tell your friends. This isn’t a startup. This is a movement 💪 Let’s kill slow learning together. – Liemar 💻  ( 3 min )

    How to Set Up a Static Backend IP for Cloud Run Revision using VPC Connector
    When deploying services on Cloud Run, the default behaviour is that the backend IP address (that is, where requests to external endpoints come from within your app), is assigned from a dynamic IP address pool. Therefore, for cases that require IP whitelisting, you need to configure the Cloud Run instance to use a static backend IP, which can be achieved through the magic✨ (read: networking capabilities) of VPC Connector. Note that we are referring to the outbound IP here, not the inbound IP which instead is how traffic gets to our Cloud Run instance and can be configured via a load balancer. Check out the Google Cloud docs here for static outbound IP addresses gcloud compute routers create my-router --network=default --region=my-region Creating router [my-router]...done.

    From Localhost to Production: A Guide to Remote Model Context Protocol (MCP) Servers
    As AI developers, we’re rapidly moving toward building more sophisticated multi-agent systems. But to make them work well, it’s not just about making smarter agents — it’s about getting them to share a common understanding of the world. That’s where the Model Context Protocol (MCP) comes in: an emerging standard that acts as a universal connector, enabling agents to access tools and data in a consistent, scalable way.

    Power Integrity Done Right: How to Build Stable, Noise-Free Systems
    Why Power Integrity Matters More Than Ever That’s where Signal & Power Integrity come together. It’s not just about feeding voltage to your components—it's about delivering power that’s steady, well-decoupled, and free of noise. Let’s break down what it really takes to get power integrity right and why it plays such a crucial role in your system’s overall performance. What Is Power Integrity? The goal? Ensure that the power rails remain within a tight voltage margin, even under demanding switching conditions. Signal & Power Integrity are interdependent—poor power integrity leads to jitter, timing errors, and signal degradation. Key Elements of Power Integrity Low Impedance Power Delivery Grounding Strategy Minimized IR Drop Common Power Integrity Pitfalls Improper Cap Placement: Reduces effectiveness at high frequencies. Split Planes Without Planning: Creates return path issues. Ignoring Current Loops: Increases EMI and power noise. No PDN Simulation: Makes it hard to predict high-speed behavior. If you're working on a design that demands high reliability, overlooking these factors can derail your project. That’s why a combined Signal & Power Integrity analysis is essential. Design Best Practices for Stable Power Keep Power/Ground Planes Solid Short, Direct Traces Use PDN Simulation Why Signal & Power Integrity Should Be Evaluated Together The most reliable designs treat Signal & Power Integrity as two sides of the same coin—evaluated and optimized as a system, not in isolation. Final Thoughts Signal & Power Integrity isn’t a luxury—it’s a baseline requirement for any high-performance, noise-sensitive design.  ( 4 min )

    Complete Guide to Turborepo: From Zero to Production
    The harsh reality is that 99% of software engineers have never heard of monorepos, let alone implemented one properly. This isn't coming from an ego-driven perspective—it's based on real-world experience with teams struggling with build times exceeding an hour for simple React applications. I've witnessed firsthand the consequences of poor monorepo implementations: teams of 20+ engineers waiting over an hour for builds on every push to the dev branch. The culprit? A React project with compressed Ant Design components being unzipped in the CI/CD pipeline, taking forever to compile.

    LLM Agent's Arsenal: A Beginner's Guide to the Action Space
    Ever sent your AI agent into the "battle" of a complex task, only to watch it fumble with a blunt sword or use the wrong weapon for the fight? When an agent fails, our first instinct is to blame its "brain" (the LLM). But the real culprit is often the arsenal we equipped it with—the collection of weapons was dull, confusing, or simply not right for the job. In our previous tutorial, LLM Agents are simply Graph — Tutorial For Dummies, we revealed that every agent is like a warrior following a simple battle plan: Assess -> Strike -> Repeat. We showed how the 'assessing' happens in a decision node that plans the next move. Now, it's time to forge the weapons used for the Strike. That 'Strike' is powered by the agent's Arsenal—the official set of weapons, tools, and spells it can draw upon. In…  ( 10 min )

    MODEL TRAINING AND EVALUATION
    model training Model training is a big part of Machine learning. it is important to ensure a proper division between training and evaluation efforts. It is important to evaluation the model to estimate quality of its predictions for the data that the model has not been trained on. After the model has interacted with unseen test data, we can deploy the model to production and monitor its to ensure business problem was indeed being addressed. Its ability to more accurately predict skils, would reduce number of transfers a customer experienced. Thus resulting to a better customer experience. Model evaluation is used to verify that the model is performing accurately. Once we have evaluated our model and began the process of iterative tweaks to the model and our data. We can adjust how fast or slow the model was learning or taking to reach an optimal value. deploying the model, to solve the business needs and meet the expectations suh as directing customer to the correct agent the first time.

    Why `h3` (from UnJS) Might Replace Express in the Modern Node.js Stack
    The Express Fatigue is Real For over a decade, Express.js has been the go-to framework for Node.js backends. But as we scaled our real-time analytics platform to 50,000+ RPS, we hit familiar pain points: Middleware soup (unpredictable execution order) Performance bottlenecks (slow routing, body-parser overhead) Lack of modern features (no built-in WebSockets, HTTP/2) Then we discovered h3—a lightweight, high-performance alternative from the UnJS ecosystem. After migrating, we saw: ✔ 2.5x faster routing 40% less memory usage Seamless integration with modern tooling Here’s why h3 might finally dethrone Express. 1. What is h3?

    Programming Entry Level: tutorial classes
    Understanding Tutorial Classes for Beginners So, you're starting your programming journey – awesome! You've probably heard about "classes" and maybe even "tutorial classes." They can sound intimidating, but trust me, they're a fundamental building block of many programming languages and understanding them will unlock a lot of power. This post will break down what tutorial classes are, why they're useful, and how to start using them. Knowing this stuff is also super helpful in technical interviews, as it shows you understand core programming concepts. Imagine you're building with LEGOs. You could just pile bricks together randomly, but it's much more organized (and fun!) to follow instructions to build a specific model, like a car or a house.

    How I'm Improving React + Node.js Projects with Simple Developer Experience Metrics
    Introduction I'm a full-stack learner diving into JavaScript, React, and Node.js. As I build apps, I realized it's not just about feature, it's about the experience of writing and maintaining the code. So I started tracking small metrics to see real progress. Here's what I've learned so far. Metric Before Now Change Why It Matters Local setup time (for me) ~30 min ~15 min −50% Quicker dev starts keep motivation high Build errors per day ~4 ~1–2 −50–75% Fewer interruptions during coding Time to fix lint errors ~10 min ~3 min −70% Keeping code clean helps readability Feedback loop (deploy → test) ~20 min ~8 min −60% I can prototype faster with faster feedback Personal satisfaction (1–5 scale) ~3 ~4 +1 point Feeling more confident in my setup Added a clear Quick Start section in README. Used simple scripts: npm install && npm start. Set up ESLint with recommended rules. Fixed the initial lint errors, so now future code stays consistent. Learned basic hot-reloading in React for faster tweaks. Simplified Node.js server restart cycle (from 20s to 8s). I now spend more time writing features and less time waiting for code to load. Build errors dropped by roughly half, debugging feels less frustrating. I rate my daily coding sessions higher, more flow, less friction. This is my journey.. not a perfectly optimized workflow. But by noticing small changes, I feel genuine progress. It shows that even simple tweaks can make coding more enjoyable and productive. Other small DX improvements I can try (like prettier, tests, or CI stuff)? How do you keep your personal projects smooth and fun? Any tool suggestions that helped you speed up development? Automate lint-fixing on save with Prettier. Try a basic test setup for one feature. Track these metrics weekly to keep pace. Making code easier to work with even for myself.. is a win. I hope sharing these small metrics helps others feel their progress, too. No need to wait for perfect projects.. start tracking small wins today.  ( 4 min )
    State of Devs 2025 Survey: Maybe Don't Call Yourself a Frontend Developer?

Let's start with an “insight” that well… isn't really one! You'll see what I mean. When talking about surveys or scientific research, you often hear that “correlation is not causation”. But what does that mean exactly? Here's a concrete example.

    The Heap Memory
    The Heap In the previous article, we discussed stack memory. In this article, we’ll complete the answer to the question: “Why is the stack faster than the heap?”, and also touch on why the heap is typically larger, but slower than the stack. A natural way to introduce heap memory is by showing a working example of how it’s used in programs. Access 🗄️ Heap memory is a region that a program accesses by explicitly requesting a block of memory from the operating system. Unlike stack memory, data stored on the heap remains valid after a function exits. For instance, when a function contains stack-allocated variables, those variables are automatically deallocated when the function returns. Attempting to access them afterward leads to undefined behavior, since the memory may have been overwrit…  ( 5 min )

Now, it's time to interact with smart contracts. These are the self-executing programs stored on the blockchain that power decentralised applications (dApps). Just like you interact with a web API to get data from a traditional server, you'll use web3.py to "talk" to smart contracts on the blockchain. A smart contract is essentially a piece of code that lives on the blockchain. Once deployed, it runs exactly as programmed, without any possibility of censorship, downtime, or third-party interference.

If you're a student or young designer thinking of freelancing, this post is for you! 1. 🚫 Don’t Undervalue Your Work In the beginning, it’s tempting to offer cheap services just to get clients. But underpricing not only hurts your confidence — it hurts the whole design community. 💡 Tip: Start with fair pricing, even if it’s slightly lower. Know your value and increase prices as your portfolio grows. 2. 🧑‍💻 Build a Portfolio Before Selling Clients want to see your skills, not just hear about them. Even if you have no real clients yet, build 3–5 solid sample projects. 💡 Tools like Figma, Framer, or Webflow help you create and showcase designs easily. 3. 🔍 Don’t Rely Only on Fiverr or Upwork Marketplaces are great, but also very competitive. *💡 Try: * Posting your work on LinkedIn or Twitter/X Joining Facebook groups for designers Writing blog posts (like this one!) about your projects 4. 🕒 Time Management Is Everything Freelancing while studying is hard — and if you don’t manage your time, both suffer. 💡 Tip: Use tools like Notion, Google Calendar, or even a paper diary. Plan weekly goals instead of daily overloads. 5. 💬 Communication Matters More Than Design Many clients don’t understand design terms. What they do understand is clear, polite, and confident communication. 💡 Practice: Writing short, professional messages. Keep updates simple and honest. ✨ Final Thoughts Freelancing as a teenager is totally possible — but it takes patience, planning, and practice. Keep learning, stay curious, and don’t be afraid to fail a few times. 🎯** Are you a young freelancer too?

    What does the terraform plan command do?
    The terraform plan command is used to preview the changes that Terraform will make to your infrastructure before actually applying them. It’s a review tool that lets you see what actions Terraform will perform, without making any real changes. What exactly does terraform plan do? Compares the current state (stored in the terraform.tfstate file or in a remote backend) with the desired configuration. Displays a detailed plan of the actions Terraform would take to reach the desired state. Actions you might see: (create): Terraform will create a new resource. (destroy): Terraform will delete an existing resource. ~ (update in-place): Terraform will update an existing resource. What is it used for? To avoid mistakes before applying changes to production. To allow team members to review changes before execution.  ( 3 min )

    🚫 Tired of typing --version commands every time you switch projects or machines?
    I was too. And honestly, it started driving me crazy. Every time I needed to check which tools I had installed — Node, Python, Docker, Git, Java, TypeScript, you name it — I’d open a terminal and type command after command… just to answer the same questions over and over. So I built something simple that solved it for me (and maybe for you too). ✅ System Versions Explorer is a lightweight Visual Studio Code extension that automatically detects and displays the versions of your dev tools — directly in the Explorer sidebar. No terminal, no guesswork. 🔄 Just open VS Code, and you’ll instantly see which tools are available and what versions you have installed. Click once to refresh. That’s it. 🔧 Try it on the Marketplace: https://marketplace.visualstudio.com/items?itemName=til0r.syv https://github.com/Til0r/system-versions I’d love your feedback ❤️ and feel free to suggest tools to support next!  ( 3 min )

    How to create an AI ChatBot and flex in front of your dumb friends
    Today, I'll show you how you can create your very own personal assistant that can answer all types of questions, and how you can host it for completely free of cost. If you're in college and your friends are dumb, you can flex in front of them. Just kidding, not just flex, you can build any type of personal robot that follows your instructions. To build this, we need 3 things: a place where we can chat, an LLM API to generate answers and a server to run the chatbot. So we use these platforms to build our app: Telegram (Telegram Bot API) OpenRouter/Krutrim Cloud (LLM API) Python Let's start with Telegram. Open Telegram and go to @BotFather to create your bot.

    Getting started with Django: Beginner summary with PyCharm
    FIRST PART: One big advantage of PyCharm is that it creates a virtual environment (venv) automatically when you make a new project — you just choose the Python version and PyCharm sets up everything for you. im gonna activate venv, pycharm comes w a venv automatically as stated above:) init_.py so next step is creating an app built a basic Django project with two separate apps (arusha and devcode). Solution: use app-named subfolders in templates: next is creating views.py for each template second template for devcode and adding urls.py for each app,later on we will hook both apps into main projects urls this is gonna drive you crazy if you are not careful.. ran server works pro tip though Remember: In Django, your views.py lives in the app folder, and your HTML files live in the templates folder. Keep your structure clean to avoid errors! In this mini project, I set up a Django project with two separate apps. Each app has its own view and its own template. I linked them with URL paths so I can open each page in the browser. This is how Django helps you organize big websites into smaller, reusable pieces And just like that, my first Django project with multiple apps runs in the browser! I learned how to create apps, views, templates, and connect everything step by step — all inside PyCharm, which made setup smooth and beginner-friendly.  ( 4 min )

    Using LLMs in 3 lines of Python
    When working with LLMs, the first thing people generally install is the openai or anthropic packages, if you’re a little more adventurous with your LLM choice it may be litellm or ollama. The issue is that all of these require a bit of code to get your started. For example, assuming you have an API key in your environment like I do, you’ll need at least this code to make an LLM call with OpenAI (also assuming you’re using the older Chat Completions endpoint). **import os from openai import OpenAI # retrieve API key from environment api_key = os.getenv("OPENAI_API_KEY") # initialize client client = OpenAI(api_key=api_key) # send a chat request response = client.chat.completions.create( model="gpt-4o-mini", messages=[ {"role": "system", "content": "You are a helpful assist…  ( 8 min )
    Cuándo usar Custom Hooks en React y Cuándo No
    Recientemente, me encontré con una publicación titulada "¿Why now devs use custom hooks instead services in React? (perspective of pre-hooks React developer). La perspectiva presentada me pareció bastante intrigante. El autor comenta cómo los desarrolladores que comenzaron su viaje directamente con React tienden a depender en gran medida de custom hooks para diversas funcionalidades o servicios. Inicialmente, pensé que esta perspectiva podría ser subjetiva o limitada a los desarrolladores dentro del círculo del autor.

    ☕️ Monday Motivation: Debug Your Monday Blues 🐛
    Monday feels like encountering a bug that only happens in production and somehow works perfectly in your local environment. Classic Monday energy. Successfully migrated from that legacy API everyone was afraid to touch. Turns out the "complex business logic" was just a bunch of if-else statements that could've been a simple switch case. Sometimes the scariest dragons are just lizards with good PR. The Rubber Duck Method: Explain your Monday to an imaginary rubber duck (or your coffee mug, I don't judge). Sometimes just saying "I have 47 Slack notifications and my build is failing" out loud makes it feel more manageable. Friday Me: "I'll definitely remember what this function does without comments" Monday Me: Stares at my own code like it's written in ancient Sanskrit Also Monday Me: "Who wrote this garbage?" checks git blame Monday Me: "Oh. It was me. On Friday." Life hack: Write code comments like you're explaining it to Monday You after a three-day weekend. Be specific. Be kind. Monday You has the memory retention of a goldfish with anxiety. ☕ Caffeine levels: Acceptable for human operation? 💻 Did I remember my laptop charger this time? 🔄 Are all my weekend side-project commits pushed? (Asking for a friend...) 📧 Email count below "abandon all hope" threshold? 🧘 Expectations calibrated to "minimum viable productivity"? You're doing great. Really. "Every bug is just a feature waiting to be discovered. And if it's not, that's what hotfixes are for."

    Bloom Filters and Cuckoo Filters
    Probabilistic data structures are essential tools for efficiently answering questions like “Is this element in my set?” when working with large-scale data. Two of the most popular structures for fast set membership queries, with tunable tradeoffs between space and error rate, are Bloom Filters and Cuckoo Filters. This article explains both data structures conceptually, and compares their strengths and weaknesses. Both Bloom Filters and Cuckoo Filters are widely used in real-world systems where memory efficiency and fast lookups are essential and occasional false positives are tolerable. Some common applications include: Databases and Caches: Used to quickly check if an item might exist before performing expensive disk or database lookups (e.g., Bigtable, HBase, Cassandra).

    Zero-Cost Abstractions in Go: A Practical Guide with Real-World Examples
    When I first started with Go, I assumed that writing clean, abstracted code meant sacrificing performance. Then I discovered zero-cost abstractions - patterns that give you maintainability without runtime overhead. Abstractions are only dangerous when they cost more than they’re worth. Rob Pike Go is often lauded for its simplicity, speed, and robust concurrency model. But beneath the minimalism lies a powerful capability: writing abstractions that don’t come with a performance price tag, what some languages call zero-cost abstractions. In this post, we’ll explore how to write idiomatic, abstracted Go code without sacrificing performance, complete with benchmarks, pitfalls, and real-world examples. What are Zero-Cost Abstractions?

    GSoC 2025 - Week 4: Jumping into Hardware Integration
    I began this week with one thought in mind: Let’s finally fix this versioning issue! During our weekly community call, I shared my blocker again. That’s when our awesome org admin Aboobacker came up with a brilliant solution: 🔁 Create a new branch from master (e.g., gsoc2025-open-hardware-library) and merge all your PRs there for now. This was the perfect way to keep things moving forward without being stuck on versioning. So, I took a fresh clone of the project, created the branch locally, added all my components, and tested everything thoroughly. And then... something unexpected happened. Guess what? ERROR: Permission to CircuitVerse/cv-frontend-vue.git denied to Nihal4777. fatal: unable to access 'https://github.com/CircuitVerse/cv-frontend-vue/': The requested URL returned error: 403 Please make sure you have the correct access rights and the repository exists. I didn’t have the rights to create a new branch on the upstream repo 😅 But no worries — I reached out to my mentor Aman Asrani and requested him to create the branch for me. Once it's there, I’ll fork it and raise all the PRs to that new branch. ⚙️ Meanwhile: Starting Hardware Integration with Web Serial API While waiting for the branch setup, I started working on this week’s task — hardware integration using the Web Serial API. I began with some research to explore all the possible approaches. I quickly got it working on our web-based simulator since I had already built a Proof of Concept (PoC) for it earlier. Now comes the real challenge — integrating it into the desktop app built with Tauri. I explored multiple options and possible ways to make it work. Next week, I’ll be diving into that and aim to complete the desktop integration too. Let’s see how it goes!  ( 3 min )

    Tune LLM(Groq Model Tune Technique's)
    Tune of Groq LLM, Its important to first understand: Important clarification: . Groq does not currently support custom model file-tunning on their platform . Instead ,Groq provides inference-as-a-service for pretrained model like LLaMA3, mistral, Gemma etc, running at extremely high speed using their custom Groq Since you can’t find-tune the LLMs on Groq, you can simulate it using these methods: Option 1: Prompt Engineering + Few-Shot Learning Embed your find-tuning knowledge directly into the prompt Prompt =””” You are an expert AI Interview asistent Q: What is the vectorization in NPL? Option 2 : RAG(Retrieval -Augmented Generation) + Groq You can build Rag System : Stor yourinterview Q & A ,PDF, CSV in a vector database (FASIS, PINECONE etc) Retrieve relevant document based on the use questions Send those documents as context to Groq LLM. This mimics tunning without touching the model. Option 3: Use Local LLM for tuning ,Groq for Inference If you want real fine-tuning, do this: Fine-tune LLaMA or Istral on your dataset(ex: Interview dataset) locally or on cloud. Then “ 2.1 Quantize the model with gguf 2.2 Deploy locally with LLM engines like Ollama,vLLM or llama.cpp 2.3 Or use Groq-compatible format in future(if supported) Regards  ( 3 min )

    Day 15 – Turning a Plain File List into a Real User Experience
    Let me be honest — today’s task wasn’t particularly glamorous. No AI models, no fancy dashboards. I spent the day working on how documents appear after upload inside Lura. Basically: I took a raw, functional file list… and made it not suck. 🧩 Why This Mattered Before today, here’s what document display looked like: - 1248dd9_contract.pdf - meeting_notes_final_final_2.docx - IMG_23423.jpg That was it. Not great. ⚙️ What I Did File type icon (PDFs, Word docs, images, etc.) Human-readable file sizes using pretty-bytes Timestamps like “uploaded 3 hours ago” Image previews on hover (for supported types) Conditional delete button based on user role On the frontend, I used useRouter() and useUser() to grab the active user’s role and decide what actions they could perform. {canDelete && ( deleteFile(file.id)}>🗑️ Delete )} {prettyBytes(file.size)} {dayjs(file.createdAt).fromNow()} 🔧 Backend Cleanup File name Size MIME type Case & Workspace linkage Uploading user Then I cleaned up the file retrieval route to send everything needed to the UI without extra processing. return await this.prisma.document.findMany({ where: { caseId }, include: { uploadedBy: true }, }); 💡 Reflections Why? Because it reminded me that good software is about humans. Not code. Not complexity. People. Our users don’t care if the backend is elegant. They care if they can see their contract at a glance. That’s it. And now? They can. ❓Question: Would love to hear about how others think about UX in places nobody notices — until it’s done wrong.

    Today learned about promise in javascript.
    what is promise in javascript? In JavaScript, a Promise is an object representing the eventual completion or failure of an asynchronous operation and its resulting value. It provides a structured way to handle asynchronous code, making it more manageable and readable than traditional callback-based approaches. const login =new promise((resolve,reject)=>{ Pending – Initial state, neither fulfilled nor rejected. Fulfilled – The operation completed successfully. Rejected – The operation failed. Creating a Promise: A new Promise is created using the Promise constructor. This executor function receives two arguments: resolve andreject. resolve(value) — called when the operation succeeds reject(error) — called when it fails Once you call either resolve or reject, the promise becomes settled (fulfilled or rejected) and cannot change. Example: function login(){ return new Promise((resolve,reject)=>{ let password = true; if(password){ resolve(); }else{ reject(); } }) } login() .then(()=> console.log("successfully login...")) .catch(()=> console.log("invalid password..."))  ( 3 min )
    Vibe Coding vs. AI Slop: Building Trust into AI Assisted Development
    AI is fundamentally changing the way we develop software. Coding assistants now generate snippets, modules, and even entire apps — accelerating workflows, eliminating repetitive tasks, and empowering teams to build and ship faster than ever. This intuitive, rapid fire style of development often dubbed “vibe coding'' feels fluid, fun, and fast. You prompt. AI completes. And you’re shipping ideas before lunch. However, whether you're using AI assistance from GitHub, Copilot, ChatGPT or even AI native editors like Cursor, there’s a flip side. Across every domain — from images and videos to content and code — we’re seeing the dark side of unchecked generation: AI Slop. In software, that means sloppy outputs that create long term problems like technical debt, opacity, and fragility. With AI co…  ( 4 min )
    You Don't Know iota
    When you delve into official libraries, open-source libraries, or any Go project, you’ll find the magical identifier iota everywhere. It plays an important role, making code more concise and clear, while improving readability and maintainability. Its applications are wide-ranging, from enumerated types to bit operations, and even complex constant expression calculations—it can do it all. In this article, I will take you on an in-depth exploration of the magical power of iota, including an introduction to iota, its use cases, practical tips, and important considerations. Within a constant declaration, the predeclared identifier iota represents successive untyped integer constants. Its value is the index of the respective ConstSpec in that constant declaration, starting at zero. The above qu…  ( 5 min )
    The Developer’s Guide to NFT Liquidity: Tracking Floor Prices Across Marketplaces
    Why This Matters NFT liquidity isn’t just about trading volume—it’s about accurately gauging realizable value. For developers building trading tools, lending protocols, or analytics dashboards, fragmented floor price data across OpenSea, Blur, LooksRare, and X2Y2 leads to: Risk miscalculations Inefficient arbitrage Broken liquidation engines Here’s how to solve it. NFT marketplaces use different: APIs (REST vs. GraphQL) Data models (e.g., floor_price vs. best_offer in Blur) Update frequencies (1 min to 1 hour) Example: Fetching "BAYC" floor prices # OpenSea opensea_data = requests.get("https://api.opensea.io/collection/bayc/stats").json() opensea_floor = opensea_data["stats"]["floor_price"] # Blur (requires wallet signature) blur_data = blur_api.fetch_collectio…  ( 5 min )
    Real-Time WebSocket Architecture: AWS IoT + Angular Integration
    1. Introduction Is it possible to interact with real-time data in our Angular project? Why do we need WebSocket? What is the difference between API and WebSocket? How do I configure the Angular project in real time with WebSocket? 1) Yes, it is possible to interact with the Angular project in real time, it is very easy to do this with WebSocket. 2) We need WebSocket because you don't need to make a request in WebSocket, it works like mqtt, it can connect directly to your iot data and give access to it. 3) The biggest difference between API and WebSocket is that you must make requests for the API at intervals. It is not possible to listen to the data between these requests instantly. However, it is enough to connect to the WebSocket once and all the necessary data will reach you ins…  ( 5 min )

    Google Agent Development Kit : Core Concept
    Recently, Google announced their Agent Development Kit (ADK), which is an open-source Python (and Java recently) library to help developers build agents. We’re entering a new phase where AI doesn’t just respond; it can act. These agents can search the web, write and execute code, read documents, call APIs, and perform many other tasks to get things done, often without needing step-by-step instructions. In this post, I’ll walk you through all the core concepts, what it is, and what it offers. Agent Development Kit is a framework to build, run, and evaluate AI agents. These agents can be simple (answering a question with a tool) or more advanced (planning tasks, calling APIs, interacting with files, or even spawning sub-agents). 💡 Google says it uses the same underlying framework as its i…  ( 7 min )

    Introducing "Output Formatter" – Clean, Readable Logs in Seconds!
    Hi devs! I recently published a new VS Code extension called Output Formatter – and if you're someone who prints a lot of logs while debugging, this one’s for you. Output Formatter is a lightweight extension (< 100kb) that automatically formats your print / console.log / System.out.println statements with: Line numbers File names Consistent, readable formatting It currently supports multiple languages including: JavaScript & TypeScript Python Java C# Go PHP Rust ...and more coming soon! Like many developers, I rely heavily on console.log() or print() for debugging during development. But the more complex the project, the harder it is to trace which print statement came from where. This leads to a lot of: console.log("here"); console.log("still here?"); console.log("WHY IS THIS NOT WORKING"); I wanted an automated way to keep my logs traceable, without cluttering them manually with filenames and line numbers every time. Thus, Output Formatter was born. Just select a log statement → use short cut key ctrl + alt + t (or right-click menu) → select "add line tracking to output"! Before: console.log("User created successfully"); After: console.log("User created successfully - user.controller.js:46"); You can install it from the VS Code Marketplace or search for "Output Formatter" in the Extensions tab. I'd love for you to try it and share your thoughts! Whether it’s a bug, a feature request, or just a thumbs-up — everything helps. You can raise issues on GitHub.

    Design-First Content Strategy: How UX Shapes Reader Engagement
    In the digital world, content is everywhere—but not all content is created equal. As readers, we’re drawn to experiences that feel intuitive, seamless, and, above all, human. That’s where a design-first content strategy comes in, and why UX writing is more than just a buzzword—it’s the secret sauce behind truly engaging digital experiences. What Does “Design-First” Really Mean? When we talk about a design-first approach, we’re not just referring to how things look. It’s about how content and design work together to guide, inform, and delight users. It’s the difference between a website that feels like a maze and one that feels like a well-lit path. A design-first content strategy means thinking about the user’s journey from the very beginning. It’s about asking: What does the reader need a…  ( 4 min )
    Your CRM is Holding Your Data Hostage. It's Time for a Jailbreak.
    Your CRM is Holding Your Data Hostage. It's Time for a Jailbreak. It was supposed to be your single source of truth. A digital home for every customer interaction, insight, and opportunity. When you first signed up for your CRM, you bought into a promise: a streamlined business, happier customers, and explosive growth. But for many businesses, that promise has curdled. Your CRM has become less of a home and more of a gilded cage. The monthly bill mysteriously creeps up. The features you need are locked behind a more expensive tier. And the most valuable asset you have — your customer data — doesn't feel like it truly belongs to you. It's trapped in a walled garden, and the landlord keeps raising the rent.

    Opensourced ML Signals Toolkit
    Hey, I just wanted to introduce my opensourced project I've been working on -- SigKit. SigKit is basically a toolbox of building-blocks for anyone who wants to play with real-world digitalized analog signals and machine learning without stitching together a dozen custom scripts. Under the hood you get: Core types like Signal, Impairment and Modem so you think in baseband, not in arrays of floats. NumPy operations for things like AWGN, phase/frequency shifts, filtering and SNR/BER calculators. PyTorch Transforms that slot right into your Compose pipeline—so adding noise or fading to every sample in your data loader is a one-liner. A PyTorch Lightning training + evaluation pipeline, complete with a pretrained modulation-classifier. Training your own custom ML model is as simple as running a script. Dataset classes and synthetic signal generators so you never have to hand-craft a CSV of complex IQ samples. (WIP) GNURadio blocks wrapping all of the above, for dropping into a live SDR flowgraph. Research labs & coursework: Teaching digital-comm concepts? SigKit turns abstract equations into hands-on Jupyter demos—generate, impair, plot, repeat. Modulation classification: Training a neural net that actually generalizes over-the-air (instead of “works on simulated data only”). SDR prototyping: Need to bounce a signal through realistic channel models before you hit the hardware? Plug in Rayleigh fading, resampling or IQ-imbalance transforms. Hackathons & demos: Spin up a quick notebook that shows off “live” impairments and classification at different SNRs—no C++ or gnuradio-block coding required. Synthetic data generation: When you need thousands of labeled IQ traces for ML, but you don’t have a tone-generator farm or unlimited SDRs. In short, if you’ve ever wished for a toolkit that treats signals more like images in PyTorch—letting you compose transforms, datasets, metrics and models in one ecosystem—SigKit has your back.  ( 3 min )

    Self-Healing APIs with MCP: No more SDKs
    Working with APIs has always been a dance between humans and machines. We write code that looks like payment.customers.create({email: "user@example.com"}), memorize method names, wrestle with documentation, and inevitably break things when APIs evolve. Meanwhile, the AI world is moving toward protocols like MCP (Model Context Protocol) designed specifically for agents. Both humans and AI need programmatic access to the same resources, so what about us human developers caught in the middle? Here's some typical example code for creating a customer with company FooCorp's SDK: import FooCorp from 'foo-corp'; const client = new FooCorp('api_key_...'); const customer = await client.customers.create({ email: 'customer@example.com', name: 'Bob Smith', }); Six months later, the API provider (…  ( 11 min )

What is this question about? event handling and event propagation in JavaScript, specifically how to control the flow of click events when you have nested HTML elements. The core problem it addresses is how to prevent a click on an inner element from also triggering the click events of its parent (outer) elements. This is a common scenario in web development where you want specific actions to happen only when a particular element is clicked, and not its containers. Solution: There are many ways to do the same but the more optimisez way is Wrapping all the divs inside one parent div having id as container. Then adding event listener o…  ( 4 min )
    Real World Project Case Study Campus Modern Web(1751293763527200)
    As a junior student learning web development, there was always a huge gap between theoretical knowledge and actual projects. It wasn't until I used this Rust framework to complete a comprehensive campus second-hand trading platform project that I truly understood the essence of modern web development. This project not only helped me master the framework but also gave me the joy of developing high-performance web applications. I chose to develop a campus second-hand trading platform as my course design project. This platform needed to support user registration/login, product publishing, real-time chat, payment integration, image upload, and other features.

    Memory Management Unit (MMU) and Translation Lookaside Buffer (TLB)
    Difficulty: Advanced Reading Time: 11 min read Last Updated: June 30, 2025 Understanding Memory Management Unit (MMU) and Translation Lookaside Buffer (TLB) The Memory Management Unit (MMU) is a critical hardware component in a computer system that handles memory management and address translation. It sits between the CPU and the main memory (RAM) and is responsible for translating virtual addresses (used by software) into physical addresses (used by hardware). The MMU plays a key role in enabling features like virtual memory, memory protection, and paging. The Memory Management Unit (MMU) primarily manages primary memory (RAM) and facilitates the translation of logical/virtual addresses into physical addresses. It plays a key role in managing the following: Virtual Memory: Ensures proce…  ( 12 min )

    Why I’ll Never Trust Carets Again
    There once was a good ol’ boy. (this poem was created by ChatGPT im not hiding it) One day, though, he had to delete his package-lock.json. Maybe it got messed up. Maybe Git went weird. Maybe he just wanted a clean install. So he did what any of us would do: rm package-lock.json && npm i But that’s when the snake bit the horse. Because somewhere in his package.json, hiding in plain sight like a viper 🐍 in the grass, were these little traps: ^1.2.3, ^6.0.1... They looked harmless; just caret (^) versions. But those carets were telling npm: “Yeah, sure, install the latest minor version. What could go wrong?” And the internet, as always, did moved on. A dependency of a dependency had released a "compatible" update. Except it wasn’t. A function behaved differently. The app crashed. Logs were useless. He didn’t even touch his code, and still… it broke. All because of a version upgrade he didn’t control. Cause ^6.0.1 isn't safe, 6.0.1 is what you do want. See ya, old buddy. Other cases i can think of where ^ are going to bite you. CI suddenly start failing: everything works locally. But a new version of a sub-dependency makes your tests fail. You waste hours debugging, thinking you broke something. Two devs. Same codebase. Different node_modules because of ^ pulling different versions. One dev gets a bug. The other can’t reproduce it. Breaking changes hidden in minor updates. If hte npm pacakge don’t follow semver. They might introduce breaking changes in a 1.4.0 that’s technically "safe" for ^1.2.3 (but it isn't). How to protect your buddy solve this: check this script: exact-versions.cjs on GitHub it will replace all those nasty ^ with the actual version you've installed. Read the lock.json and replace the ^ with the correct version. For instance this could be the output (changes to your package.json): Ride safe buddy. -- thanks for reading.  ( 4 min )

    The Invisible Post Office for Modern Software
    What Is a Message Queue? The Invisible Post Office Powering Modern Software Imagine a busy lunch hour at a popular restaurant. A waiter takes your order but doesn’t run straight to the kitchen. Instead, they clip it to a rotating order wheel or input it into a screen. The chefs pick up the order whenever they’re ready, while the waiter moves on to the next customer. This is a brilliant system it keeps waiters available, chefs unblocked, and customers moving. **This is exactly how a Message Queue works in software.** Why Do We Need Message Queues in Distributed Systems?

    The hydration error of doom
    🚨 I finally defeated the Hydration Error of Doom 🚨 This might sound dramatic, but if you’ve ever built with Next.js and dynamic components, you know what I’m talking about. For the past few days, I’ve been battling one of the trickiest bugs I’ve faced in my young LinkedIn dev journey: Hydration failed because the initial UI does not match what was rendered on the server. Yeah... that one 😅 After testing, reading, breaking things (a lot), and learning the hard way. I found the fix. ✅ dynamic(() => import(), { ssr: false }) ✅ Proper handling ✅ Client/server logic separation The best part? I didn’t just fix a bug. I leveled up in patience, problem-solving, and trust in my process. To anyone struggling through their first “impossible” bug: Keep pushing.

    🧠 Understanding JavaScript vs TypeScript: Why It Matters for Modern Development
    In the fast-paced world of web development, choosing between JavaScript and TypeScript is more than just a syntax preference — it’s a design decision that impacts scalability, maintainability, and team productivity. JavaScript (JS) is the core scripting language used in browsers. It’s dynamic, loosely typed, and incredibly versatile. You can build everything from simple websites to powerful server-side applications using Node.js. Universally supported in browsers Mature ecosystem (React, Express, Vue, etc.) Quick to prototype and iterate No static type checking Runtime errors are common Refactoring large codebases is risky TypeScript (TS) is a superset of JavaScript that adds optional static typing, modern ES features, and tooling support. It compiles down to JavaScript, so it works anywhere JS does. Type Safety: Catch bugs at compile time instead of runtime. Editor Support: Autocomplete, IntelliSense, and inline documentation. Better Refactoring: Rename variables or interfaces with confidence. Scalability: Great for large teams and growing codebases. function greet(name: string): string { return `Hello, ${name}`; } In plain JavaScript: function greet(name) { return 'Hello, ' + name; } The TS version gives you better developer tooling and type guarantees. You don’t have to rewrite your app. You can gradually adopt TypeScript by: Renaming .js files to .ts Adding tsconfig.json Enabling strict mode for better type checking Fixing type errors progressively If you’re building a small script or a quick MVP — JavaScript is fast and flexible. But for robust, scalable, production-grade apps, TypeScript is becoming the de facto standard in modern development. ✅ TLDR: JavaScript is fast and flexible, but TypeScript adds safety and structure. Use JS to start, switch to TS to scale.  ( 3 min )

    15 Go Packages Worth Your Time
    I’ve worked with Go for years, building web apps, CLIs, microservices, daemons, and all the in-between stuff nobody talks about. If you’ve worked with Go long enough, you know the standard library is solid, but you also know it’s not always enough. Most problems you’ll run into have already been solved—cleanly, efficiently, and without the nonsense—by libraries maintained by people who know what they’re doing. So instead of throwing out a list of “cool” Go packages, here’s a hand-picked set of 15 libraries that are actually worth using, based on real-world experience. These are things I’ve reached for again and again, and they’ve never let me down. If you’re building anything that touches config, flags, or maps—or you just want cleaner, testable code,these are the packages that’ll help you…  ( 6 min )

    Auto-Investing: How I Stopped Chasing the Perfect Entry Point
    For the past few months, I’ve been using auto-investing in crypto — and honestly, it’s one of the smartest decisions I’ve made in this space. Before that, I was like most people: trying to time the market, checking CoinMarketCap every hour, watching for Elon Musk tweets, and constantly wondering “Is this the dip?” or “Should I wait another day?” It was exhausting — mentally and emotionally. At some point, it hit me: why not treat my personal investing like I treat my development workflow? I don’t manually deploy code every time — I have pipelines, triggers, schedules. So why was I manually trying to “catch the dip” like it’s some kind of sport? That’s when I started setting up auto-invest plans. For example, I have one that buys ETH every month — but only if the price is between $1,900 and…  ( 4 min )

    Shut up, Meg: Why Devs Don't Speak Up, and What it Costs
    I stood in front of a room full of leaders and told the truth: our developer experience was broken. I gave an honest look at how painful our tooling and processes had become: how the platforms that were supposed to enable developers had turned into something that actively slowed them down instead. We’d lost sight of the goal, and I wanted to raise the alarm that we had. Instead of helping teams move fast and build safely, we were optimizing for everything except the developer experience: Security, Compliance, Governance, Cost. Oh, sure, those are all very important, but we were doing it at the expense of the very folks that we needed to empower. Dev was frustrated. Ops was frustrated. Projects were delayed, and it was all just accepted as "the cost of doing business". I made my case, and …  ( 6 min )
    What is DevOps? A Practical Guide for Beginners
    “DevOps isn’t a role. It’s a mindset — and a toolchain.” In today’s fast-paced digital world, businesses are under pressure to deliver high-quality software faster than ever before. Traditional software development and IT operations often function in silos, leading to slow deployments, miscommunication, and unreliable systems. That’s where DevOps comes in.

    DAY 14-DEPLOYING VIA GIT
    Hi all....yesterday I had posted on how to deploy directly through GitLab without using the Terminal or Git Bash......today I will tell you how to do the same via terminal. 1.First create a project via GitLab using the steps I mentioned yesterday. Next go to the local folder present in your computer which contains the files necessary for deploying (i.e) index.html and style.css. Open the folder right click and select Open with Terminal or Gitbash. 3.Go to your project in Gitlab and from the code tab copy the URL present under Clone with HTTPS. Go to the terminal and type in the following command git clone (copied URL) git add . git commit -m "Some comment" git push Press Enter after typing each line of code. Once all your files are successfully pushed refresh your project page in Git and the files will be displayed. 4.Then click on + button in your project repository and click on create new file and type the name as .gitlab-ci.yml and enter the following code: pages: stage: deploy script: - mkdir public - cp index.html public/ artifacts: paths: - public only: - main It will suggest creating a template file but copy the above code only. Also if your images and css are in a separate file or folder you need to make them also public by adding the following code: script: - mkdir public - cp index.html public/ - cp-r Folder(or)Filename/public Once this file is created,GitLab will automatically start the deployment process. 5.Go to menu icon on the top left corner of your project and click on Deploy->Pages to check the status of your live site. 7.After few minutes your site will become live and the URL will be displayed in the Pages tab. This is how we can create a live site using terminal....that's all for today...see you all in the next post!  ( 3 min )

    📚 Introduction Hey, algorithm explorers! 🧭 Today, we’re diving into a classic in the world of graph theory — Dijkstra's Algorithm. Whether you're navigating road maps, network packets, or game AI, this algorithm plays a pivotal role in finding the shortest path from a source node to all other nodes in a graph. Let’s unpack it, step by step. You are given: A graph represented with nodes and weighted edges (non-negative). A source node from which we want to compute the shortest path to every other node. Your goal: Find the minimum distance from the source to each node using Dijkstra’s algorithm. This algorithm works for graphs with non-negative weights only. The core idea is greedy: Start at the source node with distance 0. Repeatedly pick the node with the smallest known distance that h…  ( 5 min )

    ⚔️ The Josephus Problem Explained: Constant-Time Solution for k = 2
    🧠 Problem Summary The Josephus problem is a classic theoretical problem in computer science and mathematics. It is stated as follows: Given n people standing in a circle, every k-th person is eliminated in a round-robin fashion. After each removal, counting resumes from the next person. The process continues until only one person remains. The problem is to find the position (1-based or 0-based) of the last remaining person. For example, with n = 7 and k = 3, the order of elimination is: Eliminated: 3 → 6 → 2 → 7 → 5 → 1 → Survivor: 4 This general problem can be solved recursively in O(n), but in a special case when k = 2, it admits an O(1) time closed-form solution. When k = 2, the Josephus problem has a beautiful binary pattern. Here’s what happens: People are eliminated in powers of two: the 2nd, 4th, 6th, etc. The safe position follows a pattern that can be expressed with binary shifts. If n is the total number of people, and L is the largest power of 2 ≤ n, then: Josephus(n) = 2 × (n - L) This gives the position of the last remaining person (1-based index). class Solution { public: int josephus(int n) { int l = 1 << (31 - __builtin_clz(n)); // Largest power of 2 <= n return 2 * (n - l) + 1; } }; __builtin_clz(n) returns the number of leading zeroes in n. 1 << (31 - __builtin_clz(n)) computes the largest power of 2 ≤ n. function josephus(n) { const highestPower = 1 << (31 - Math.clz32(n)); return 2 * (n - highestPower) + 1; } def josephus(n): l = 1 << (n.bit_length() - 1) return 2 * (n - l) + 1 This elegant O(1) formula only works when k = 2. For general k, you need simulation (O(n)) or recurrence (O(n log k)). The Josephus problem is a great blend of bit manipulation, recursion, and mathematical pattern recognition. If you found this helpful, drop a ❤️ and follow for more deep dives into classic CS problems! Happy problem-solving! 🧠✨  ( 4 min )
    From Dev Blog to AI Discovery – How to Rank Your Content in Generative Search

    Optional Chaining (.?) in JS — Write Shorter & Safer Code!
    Handling undefined or null checks in JavaScript used to mean a bunch of messy if statements or long && chains.

    Day 11 - Building the Document Management System
    I focused on implementing one of the key features for any legal platform: document management. Since Lura is a case-centric system, each legal case can hold multiple documents. These need to be uploaded, listed, downloaded, and (by authorized users) deleted. 📁 Goals Allow users to upload documents to specific cases Store document metadata in the database Link each file to a workspace and case Allow admins to delete files Prevent unauthorized access to documents 🔨 Stack & Tools Used Frontend: Next.js + FormData for file uploads Backend: NestJS + Multer (file middleware) ORM: Prisma Database: PostgreSQL File Storage: Local for now (to be moved to cloud storage later) 📦 Backend – File Upload API @Post('upload/:caseId') @UseInterceptors(FileInterceptor('file')) uploadDoc(@UploadedFile() file, @Param('caseId') caseId: string) { return this.docService.storeFile(file, caseId); } Files are saved locally in /uploads and registered in the Document table with their name, caseId, and uploadedAt timestamp. 💻 Frontend – Upload Interface with a button to trigger submission via fetch: const formData = new FormData(); formData.append("file", selectedFile); await fetch(`/api/upload/${caseId}`, { method: "POST", body: formData }); Once uploaded, the new document appears in a list with its name and an option to delete (visible only to Admins). 🧹 Delete Function with Permissions @Delete(':docId') @UseGuards(AuthGuard, RoleGuard) deleteDoc(@Param('docId') id: string) { return this.docService.delete(id); } ✅ Key Lessons & Takeaways NestJS makes handling file uploads smooth with built-in interceptors RBAC is essential — users shouldn’t even see buttons they can’t use File metadata (not just the file) is important for traceability Uploading should feel seamless, especially in a legal tool where reliability matters ❓Question for You How do you handle secure file uploads in your apps — and do you prefer local or cloud storage?  ( 4 min )

    Automating the Boring Stuff — Beyond Cron Jobs with Python 🐍
    If you're still relying on cron for your backend workflows… it’s time to upgrade. In one of my recent projects, I built an async-compatible task runner that completely replaced traditional cron logic. Inspired by the limitations I kept hitting with system schedulers, I built a modular runner that now powers dozens of my automated jobs — from SEO link drops to data fetching scripts. 🛠️ Why I Ditched Cron: No native retry logic Difficult to manage across servers Zero visibility into what's working and what’s silently failing 💡 My Solution: FastAPI for control endpoints ThreadPoolExecutor for concurrency Simple YAML-based task definitions Optional webhook triggers for external events The whole thing runs under the hood of a larger project called Delta Executor, which also handles off-page SEO workflows and structured link automation. ✅ What I Gained: Dynamic control (pause/resume/kill) One tool for everything: API pings, sitemaps, link indexing, etc. If anyone’s building automation systems and tired of cron spaghetti, I’d love to hear how you’re solving it. And if you’re interested, I can open-source a minimal version of this task runner.  ( 3 min )

    Essential SQL Commands for Developers (With Code Samples)
    SQL lets you control and query relational databases with precision. This guide shares the key commands developers need to know, along with examples you can drop into your projects right away. Key Commands You’ll Use Regularly SELECT SELECT name, age FROM users WHERE age > 25; Retrieves users older than 25. INSERT INSERT INTO users (name, age) VALUES ("Maya", 29); Adds a new user. UPDATE UPDATE users SET age = 30 WHERE name = "Maya"; Changes Maya’s age. DELETE DELETE FROM users WHERE name = "Maya"; Removes Maya from the table. CREATE TABLE CREATE TABLE products (id INT, name VARCHAR(100)); Sets up a table for products. JOIN SELECT U.name, O.amount FROM users U INNER JOIN orders O ON U.id = O.user_id; Combines user and order data into one result. LIMIT SELECT * FROM users LIMIT 10; Returns the first 10 rows from the table. FAQ Is SQL still worth learning? Absolutely. It’s the core of most analytics, backend systems, and admin tools. Yes for the basics, though some systems offer extra features or slightly different syntax. DbVisualizer is a strong option—it works with many databases and includes helpful dev features. Start chaining commands, use subqueries, and explore performance tuning. If you’re building apps or working with data, these SQL commands will show up constantly. Learn them once, and they’ll serve you across every project, from data reporting to app development. With the right client, writing these queries becomes even faster.

    How to Write a Software Project Proposal: Complete Template & Guide
    Introduction As a Software Architect, I was recently assigned to prepare a software project proposal for a client, which also involved conducting a requirement analysis in collaboration with our Business Analyst team to identify the functional and non-functional requirements. A significant part of software engineering is the systematic process of requirements engineering and the preparation of a comprehensive document known as the Software Requirements Specification (SRS). This document serves as an agreed-upon scope and working modality among all stakeholders. However, preparing such a document has not been within my comfort zone, as my experience over the past few years—as a Senior Software Engineer—has been primarily focused on development and reviewing technical artifacts. After cond…  ( 5 min )
    ⚡️ Stop Writing Flaky Tests: Your Foundational Guide to Async in Playwright
    🤖 In our last article, we built a scalable Page Object Model, giving our tests a solid architectural blueprint. We organized our locators and actions into clean, reusable classes. But even the best blueprint can't prevent a house from collapsing if the foundation is shaky. In test automation, that shaky foundation is often a misunderstanding of asynchronicity. This article tackles that head-on. We'll explore why Playwright is inherently asynchronous and how to manage it. You will learn the three essential pillars of async mastery: async/await: The fundamental syntax for controlling the flow of your tests. Promise.all: The secret to speeding up test execution by running operations in parallel. try/catch: The safety net for building robust tests that don't crash unexpectedly. Masterin…  ( 8 min )
    Jest 30: Más Rápido, Inteligente y Listo para el Futuro. ¿Es Hora de Actualizar?
    Después de una espera que pareció una eternidad en el vertiginoso mundo del desarrollo de software, el equipo de Jest ha lanzado la versión 30. Y permíteme decirte, la espera ha valido la pena. Esto no es una simple actualización incremental; es una reinvención fundamental que aborda deudas técnicas de larga data, responde a las críticas de la comunidad y reafirma a Jest como un titán en el panorama de las pruebas de JavaScript. Durante años, los desarrolladores hemos tenido una relación de amor-odio con Jest. Adoramos su simplicidad de "cero configuración" y su potente ecosistema, pero a menudo nos hemos enfrentado a tiempos de ejecución lentos y a un consumo de memoria descontrolado en proyectos grandes. Jest 30 no solo pule los bordes ásperos, sino que reconstruye los cimientos. El prob…  ( 5 min )

    The Crumb Trail: Managing Cookies in Next.js🍪
    Let me tell you a story about how I once spent an entire afternoon debugging why my user preferences weren't persisting, only to discover I'd set a cookie with path=/admin while my app was running at path=/. That was the day I vowed to master cookie management in Next.js, and today, I'm going to share that hard-earned knowledge with you. Cookies are like the breadcrumbs of the web (hence the terrible pun in this post's title). They help us remember user preferences, maintain sessions, and keep our applications stateful. But much like real breadcrumbs, if you don't manage them properly, you'll end up with a mess. Here are the two files you'll need to implement in your project: lib/cookies.ts - The Core Utility export type CookieOptions = { days?: number; path?: string; domain?: s…  ( 6 min )
    Programming as a Art - Chapter - 10
    Every era of art has its masterpieces — from Da Vinci’s Mona Lisa to Beethoven’s Symphonies. In the world of programming, masterpieces are not framed on walls — they run on screens.

    How to Choose and Actually Finish an Online Course
    These days, there are so many online courses available to help us learn new skills or improve the ones we already have. Often, we find a course that looks exciting. We start it with full motivation, but after a few days or weeks, we lose interest, get distracted, or jump to another course. This happens to a lot of people and it’s not always your fault. Sometimes the problem is with the course itself, sometimes with how we approach it. I’m a frontend developer and have taken many courses (you can even see some of them on my LinkedIn). After lots of trial and error, I’ve created a simple strategy that helps me stay focused and actually finish what I start. Let me share it with you: This is the most important factor for me. I always try to pick short courses that I can finish in 1 to 3 weeks.…  ( 4 min )
    Making Sense of Cloud Costs with the FOCUS Framework
    Why the FOCUS Framework Matters in Real-World FinOps When you’ve worked with cloud bills for long enough, a few truths become obvious. Every cloud provider structures data differently Normalizing cost and usage data across teams is a pain Building dashboards is easy — making them reliable and actionable is not That’s where the FOCUS Framework steps in.

    How AI Code Review Tools Are Transforming Code Quality and Developer Velocity
    Why teams are adopting AI reviewers to boost code quality, cut review time, and scale engineering excellence Code reviews are a cornerstone of healthy engineering teams. They catch bugs, promote learning, and keep codebases clean. But as teams scale, the code review process starts to break. Pull requests pile up. Senior engineers get swamped. Review quality drops, or slows delivery. Now, a new kind of teammate is stepping in: the AI-powered code reviewer. These tools don’t just check formatting. They surface logic issues, enforce best practices, and provide structured feedback. The result? Faster shipping, fewer bugs, and cleaner code across the board. When a team of five becomes fifty, reviewing code stops being a one-off responsibility. It becomes a throughput problem. Most devs agree re…  ( 5 min )
    Guide to Data Protection on Telegram
    Telegram has long ceased to be an anonymous space. Knowing just your ID (@username) or phone number, someone can learn almost everything about you. From the groups you belong to, what you wrote there in the past (including some deleted messages that may still exist in archives), whom you talked to, which voice notes or media you posted — even private chats you're a part of (if they were once public), your previous usernames, and potentially even personal data, geolocation, and more. The main source of such information? Telegram bots. How to become a "ghost" on Telegram? • Don’t use unknown Telegram bots. • Don’t use your primary phone number. • Hide your name. • Avoid using @usernames. • Don’t share personal information. • Configure your privacy settings. Remember: Absolute anonymity on the internet is impossible. You always leave digital footprints that can be traced back to you. But minimizing them — is absolutely possible.  ( 4 min )

    10 AI Tools That Cut Documentation Time by 70% (Real 2025 Benchmarks)
    Let's be honest, documentation is the necessary evil of software development. We know it's crucial for maintainability, onboarding, and long-term project success, but it's also the task that makes most developers groan internally. 💡 Recent studies show that developers spend 20-30% of their time on documentation-related tasks, which translates to roughly 8-12 hours per week for a full-time developer. But what if I told you that AI tools could cut that time by 70%? After extensively testing 15+ AI documentation tools across real-world projects in 2025, we've identified the top 10 that deliver measurable time savings without compromising quality.

    Kubernetes Cost Nightmares: Why Most Startups Overpay on EKS (And How to Fix It)
    Your monthly AWS bill just arrived, and that sinking feeling hits again. What started as a "lean" Kubernetes deployment is now eating 40% of your runway. Sound familiar? Average startups waste $50,000-$200,000 annually on EKS overprovisioning But the real kicker? Most founders don't discover this until it's too late—when the runway is short and investors are asking hard questions about unit economics. The CPU Overprovisioning Death Spiral Your developers set CPU requests "to be safe," but safe for them means financial suicide for you. Here's what typically happens: # What developers request resources: requests: cpu: "1000m" memory: "2Gi" limits: cpu: "2000m" memory: "4Gi" # What actually gets used # CPU: 50-100m (5-10% utilization) # Memory: 200-400Mi (10-20% utili…  ( 6 min )
    AWS Shell Scripting
    Intro I deployed my first two services to AWS Fargate earlier this month --a node/typescript websocket server and a fastapi python microservice. But this post isn't about either service, it's about shell scripting as indicated by the title. As a sanity measure, I highly recommend using a script similar to the one included below to pull info for all services/instances you have configured with aws. Before doing so, ensure you have the aws cli installed and your credentials stored in ~/.aws/credentials and/or ~/.aws/config if using Mac or Linux, else store them in %USERPROFILE%\.aws\credentials and %USERPROFILE%\.aws\config if using Windows. Tip: If you're using WSL2 like me, you'll likely want to keep this in your WSL2 distro environment (using the linux/mac locations for your credentials…  ( 4 min )
    Ollama: How to Easily Run LLMs Locally on Your Computer
    I just found an interesting open-source tool called Ollama. It's a command-line application that lets you run Large Language Models (LLMs) on your computer. So I wanted to know more about this and tried it out on the weekend. So here I am sharing what I learned when I used Ollama.

    Becoming a Better Developer with Vibe Coding
    There's an unfortunate stereotype with vibe coders these days; quite a number will argue that vibe coders don't really care about software craft, maintenance, bug fixing and the other nuances that come with building quality software. As someone who's been writing code for over a decade, my primary tool of trade has been fullstack TypeScript (with Angular on the UI). However, I've always wanted to build side projects in other languages or frameworks that I considered interesting: Realtime applications with Erlang/Elixir OTP UI applications in React Web scraping & data analytics with Python...etc With life and other commitments, it can really be difficult to pull these off as it does take significant amount of time to learn new cognitive skills. With vibe coding, I feel excited to kickstart these projects once again. My approach however won't be to just blindly trust the AI to deliver the code based on my prompts alone. I intend to also use this opportunity to learn from the generated code. As a general rule, I always try to ask the AI what the code is intended to do and why it was done in that way. Here are other ways vibe coding can make you a better developer: Ask the AI to create the generated pseudocode from time to time instead of just going straight to the "answer". If learning a new syntax, ask the AI to translate the code to language or framework you're familiar with. For instance, for a piece of Elixir code I can ask the AI agent how this could be done in Angular. This way I get to bring it to a world I'm more familiar with. If possible, follow a TDD (Test Driven Development) approach where you tell the AI to generate tests before writing the business logic. This way you get to actually know what your logic is intended to do.  ( 3 min )

    Why Testing Is the Last Bottleneck in Modern Software Development
    We’ve automated design. But testing? Still stuck in the past. While dev tools have exploded — with AI copilots like Cursor, Bolt, and Lovable turning code into a creative, collaborative flow — QA hasn’t moved. Development’s fast. Clean. Intuitive. “Vibe coding” is real. You build, you ship, you iterate — all in the same day. But testing? Still slow. Still manual. Still a grind. Despite how far modern software development has come, testing remains the last unbroken bottleneck — the tedious step that holds everything else back. It’s the one piece of the pipeline that hasn’t caught up with the speed of modern product teams. Let’s talk about why that is — Over the past decade, tools like Vercel, Netlify, GitHub Actions, and even AI pair programmers like Copilot have transformed how we build an…  ( 4 min )

    Why AI Won’t Replace Web Developers (But Might Replace Lazy Ones)
    AI is changing everything — from how we write code to how users interact with our apps. But here’s the truth: Web developers aren’t going anywhere. Lazy developers might. The New Reality Suggest code Explain APIs Even scaffold simple apps But they don’t replace problem-solving, system design, debugging, or the human layer of UX. Those are things developers still need to own — and own better than ever. What It Actually Means for Us Relies on StackOverflow copy-paste with zero understanding Doesn’t care about accessibility, security, or optimization Avoids documentation or testing ...then yes — AI might do your job better and faster. But if you: Think critically Know when to use and when not to use AI Care about product value and user experience Write code you understand and can explain Then you’re 10x more powerful with AI, not replaceable by it. Final Thought AI is a tool. A damn good one. But tools don’t replace craftsmen.  ( 3 min )

    Rise of OpenJDK & Oracle vs Others
    Welcome back to Journey Through Java! 👋 Over the past week, we've explored Java's origins, editions, philosophy, and ecosystem. Today, we're diving into one of the most significant shifts in Java's history—the rise of OpenJDK and how it changed the entire Java landscape forever. If you've ever wondered why there are so many different Java distributions today (Amazon Corretto, Eclipse Temurin, Azul Zulu), or what happened after Oracle acquired Sun Microsystems, this post will clear up all the confusion. In January 2010, Oracle completed its acquisition of Sun Microsystems for $7.4 billion. With Sun came Java—the programming language, the JVM, and the entire ecosystem that powered millions of enterprise applications worldwide. This wasn't just a corporate acquisition; it was a seismic shif…  ( 12 min )

    Analysis of the DORA 4 Keys from the Perspective of the Toyota Production System (TPS)
    Who is this article for? This article is for: Anyone who is about to introduce software development productivity metrics to their team.Those who already use these metrics but want to revisit “Why these metrics?” and add their own insights Just an ordinary web programmer. Currently studying DevOps. Why Toyota? It’s a fair question.(If you’re already using the DORA 4 Keys and wondering “Why bring up Toyota?” please read to the end!) You won’t find many articles on the web that directly link the DORA 4 Keys and the Toyota Production System, but understanding TPS can give you a deeper grasp of the 4 Keys. That’s because the origins of “Lean” (and therefore DevOps) are deeply rooted in TPS. If you look into academic DevOps literature, TPS pops up everywhere as a keyword. Personally, I disco…  ( 7 min )
    [📝LeetCode #290] Word Pattern
    🎀 The Problem Given a pattern and a string s, find if s follows the same pattern. Here follow means a full match, such that there is a bijection between a letter in pattern and a non-empty word in s. Example: Input: pattern = "abba", s = "dog cat cat dog" class Solution { public boolean wordPattern(String pattern, String s) { HashMap map = new HashMap(); int count = 0, wordcount = 0; String word = ""; for (int i = 0; i < s.length(); i++) { char letter = s.charAt(i); if (count == pattern.length()) return false; if (letter != ' ') word += letter; if (i == s.length() - 1 || word != "" && letter == ' ' ){ char key = pattern.charAt(count); …  ( 4 min )
    [📝LeetCode #205] Isomorphic Strings
    🎀 The Problem Given two strings s and t, determine if they are isomorphic. Two strings s and t are isomorphic if the characters in s can be replaced to get t. Example: Input: s = "egg", t = "add" Explanation: The strings s and t can be made identical by: class Solution { public boolean isIsomorphic(String s, String t) { HashMap map = new HashMap(); for (int i = 0; i < s.length(); i++) { if (!map.containsKey(s.charAt(i)) && !map.containsValue(t.charAt(i))) map.put(s.charAt(i), t.charAt(i)); else if (map.containsKey(s.charAt(i)) && map.get(s.charAt(i)) != t.charAt(i)) return false; else if (!map.containsKey(s.charAt(i)) && map.containsValue(t.charAt(i))) return false; } return true; } } ✖️ Runtime & Memory I was not sure, and I am not sure why my code takes a long time, although I use a HashMap. My favorite YouTuber also suggested the HashMap. Nikhil Lohia's Isomorphic Strings (LeetCode 205) In LeetCode, I found that the array method is faster than HashMap, so I would try with this array method. class Solution { public boolean isIsomorphic(String s, String t) { int[] slist = new int[256]; int[] tlist = new int[256]; for (int i = 0; i < s.length(); i++) { if (slist[s.charAt(i)] != tlist[t.charAt(i)]) return false; slist[s.charAt(i)]=i+1; tlist[t.charAt(i)]=i+1; } return true; } } Why int[256]? A char in Java is 16-bit, but standard ASCII characters only use 7 bits (0-127). Extended ASCII uses 8 bits (0-255), so int[256] covers all possible ASCII characters. i + 1 avoids ambiguity with default 0.  ( 4 min )

    👹 Longest Binary Subsequence K – LeetCode 2311 (C++ | JavaScript | Python )
    👋 Hey, binary sleuths! 🕵️‍♂️💡 Today, we dive into a clever bit manipulation puzzle — LeetCode 2311: Longest Binary Subsequence Less Than or Equal to K. It’s all about squeezing the longest subsequence out of a binary string that forms a number ≤ k. Let's decode this one together! 🧠 You're given: A binary string s An integer k You need to return the length of the longest subsequence of s such that: That subsequence forms a valid binary number ≤ k Leading zeroes are allowed Subsequence must respect the original order of characters To maximize the length of the subsequence: Include all '0's — they do not increase the binary value. Greedily add '1's from the right side — since binary is weighted from right to left, rightmost '1's have smaller impact. Stop adding when the resulting n…  ( 4 min )
    Understanding Singleton Design Pattern: A Simple Guide
    What is Singleton Pattern? Imagine you have a TV remote at home. You don't need 10 remotes for the same TV, right? One remote is enough for everyone in the family to use. The Singleton pattern works the same way - it ensures that a class has only one instance and everyone uses that same instance. Think about these real-world examples: Database connection - You don't want 100 connections to the same database Printer - Multiple print jobs should go to the same printer Settings/Configuration - Your app should have one set of settings, not multiple copies Let's say we're building a Logger class to write logs to a file.

    AI Ethics: Are We Creating a Monster?
    Can We Trust a Machine With a Moral Compass? Here's something to chew on: A recent survey found that nearly 70% of Americans don’t trust AI to behave ethically. And honestly? Can you blame them? Imagine sitting across from a bank officer, applying for a loan. But instead of a human, it’s an AI that’s digging through your data. Spoiler alert: you get denied—not because of anything you did, but because some old, biased data says people who look like you have defaulted more often. Yikes, right? Or picture this: a hospital uses an algorithm to prioritize treatment. The AI decides who gets that urgently-needed organ transplant… and who doesn’t. And there's no human double-checking.

Sure. Skepticism? Definitely. Maybe even a touch of “Wait… am I about to be replaced by a bot?” I’ve been there. It’s a weird combo of curiosity and existential dread. The real talk? Marketing content is needed faster than ever—blogs, emails, case studies, social posts, video scripts. It’s a nonstop buffet. And we humans? Well, we’ve got creat…  ( 14 min )

    Rails on Jets: Serverless Active Record? Here’s What Broke
    "We ran Rails in AWS Lambda—and lived to tell the tale." Serverless promises zero infrastructure, infinite scale, and pay-per-use pricing. But when we tried running a Rails app with ActiveRecord on Jets, we hit walls you won’t find in the docs. Here’s what worked, what catastrophically failed, and how we fixed it. 1. The Dream vs. The Reality What We Expected ✅ No servers to manage Automatic scaling during traffic spikes Cost savings (only pay for execution time) What We Got ❌ Cold starts (5+ seconds for the first request) Database connection storms (Lambda + ActiveRecord = 💥) Mysterious timeouts (Rails + 15-second Lambda limit = 😱) 2.

    JavaScript Gotchas That Still Catch You Slipping (Even After Years)
    Yep — even an empty array is truthy. Try this: if ([]) console.log("true"); // It runs! Then your “harmless” condition silently fails elsewhere. Been there? These tiny quirks can break production logic in the weirdest ways. The Scope Chain Dance var count = 1; if (true) { var count = 2; } console.log(count); // 2 Now switch to let or const and the behavior changes. Lesson: If you're still casually using var in 2025 — you're skating on thin ice. OOP vs Functional Someone asked me: “Which is better — OOP or Functional? My answer: Depends. OOP helps when you're modeling real-world structures (ex: User, Order, Cart) Real Use: I mixed both in a React-Redux app — OOP-style classes for config, FP-style for transformation — and it worked beautifully. The DOM: Knowing It vs Using It Many devs use JS or React to manipulate the DOM — but few understand how it really works under the hood. document.body.children[0].textContent; Looks old-school? It once helped me debug a script before React mounted. Why it matters: DOM knowledge is critical when: Tuning performance Fixing bugs in third-party scripts Understanding how React actually mounts JSON.stringify() vs JSON.parse() const data = JSON.stringify({ price: 100 }); const parsed = JSON.parse(data); Clean, right? Now try: JSON.parse(undefined); Lesson: Always validate before parsing. Use try...catch: try { const safeParsed = JSON.parse(data); } catch (error) { console.error("Parsing failed:", error); } Final Thought JavaScript doesn’t just run — it behaves. Sometimes… unexpectedly. And knowing those behaviors is what separates a dev from a debugger. What’s your most “Wait… what just happened?” JS moment? Drop your logic bugs, type coercion fails, or memory leaks below , Let’s laugh, cry, and learn together.  ( 4 min )

    Software Architecture Styles : Monolith, Modulith, Micro-services, which option is better for you
    As software developers we have multiple tools at our disposal so that we can build softwares, if we take the example of softwares built with Java, we have methods, and once we have a bunch of methods that are related we can group them together into classes, and these classes can be grouped in packages, and these packages can be externalized in modules. Software Architecture is all about how all these tools are linked and are having relationships between each other. In this article we are going to cover the most commonly used software architecture styles including monolith and micro-services, then we will introduce another style that is considered as a middle ground between the 2 styles and that is called modulith (modular monolith) What is a monolithic application In a monolithic style, t…  ( 6 min )

    Spelling Checker - NLP
    Why you need Spell Checker? A spell checker is a software feature, often integrated into word processors, email clients, or other text-based applications, that identifies potential misspellings in text by comparing the words to a built-in dictionary. It highlights potential errors, often with underlines (red for spelling, green for grammar in some programs), and provides suggestions for corrections. User searches: "restarant near me" Spell checker in Google understands: "Did you mean: restaurant near me?" It corrects the typo silently and gives you correct results. Saves Time, building spell checker from scratch requires big dictionary of correct words, rules of grammar, possibly training a model on thousand of example would be better choice. Before starting this model you must get familiar with String, Regular Expression and nltk library. I will start in next series with Finding the probability distribution  ( 4 min )

    How AI in Art Boosts, Not Replaces Creativity
    Is AI the End of Art or Its New Muse? Did you know that over 60% of creatives have already used some form of AI in their workflow? Yep, it surprised me too. And if your first reaction is somewhere between “heck no” and “cool... but scary,” you’re not alone. When we hear the phrase AI in art, it’s easy to imagine robots painting masterpieces and stealing gallery space from flesh-and-blood artists. But honestly? That’s not the vibe. Not even close.

    Confession: I’m a Developer Who Just Started Using Git Properly
    Even after being involved in the field of Computer Science for the past 7 years (as a student and a professional), I am still not as proficient in Git as I would like. This is because I used TortoiseSVN in my previous job. TortoiseSVN uses a centralized version control system (CVCS) model, where the "trunk" typically represents the main development line or the latest stable version. While it’s great for handling large binary files, it has some limitations: "Branching" is implemented as directory copies, not as first-class objects A stable network connection is required to interact with the central repository Developers do not usually have a full local copy of the repository history As a result, I rarely needed to think about distributed workflows or advanced branching strategies — two key parts of Git. Git is a distributed version control system (DVCS) that gives each developer a full local copy of the repository. That means: You can work offline Branching and merging are fast and flexible Collaboration scales better across teams In hindsight, I believe Git is not just better — it’s essential for modern developers. Here are two excellent resources that helped me get started: 📺 Git Crash Course For Beginners 🌳 Learn Git Branching (interactive visual tool) These gave me both the big picture and the hands-on skills I was missing.

    Why E2E Tests Should Go Beyond the Browser
    The End-to-End Illusion End-to-end testing promises to simulate real user journeys, but in practice, most tests stop at the UI. A user signs up, submits a form and an assertion confirms that a success message appeared. Test passed. But in reality, the journey doesn’t stop there. Most applications rely on email at some point in the user flow, whether it’s for verifying an account, resetting a password, confirming a booking or delivering a receipt. If your test stops at the frontend, you’re not catching the moments where real users are most likely to get stuck. Modern web applications are made up of many interconnected parts. When we talk about end-to-end testing, we should be testing the entire journey, not just the browser interface. Here are a few common flows that extend into email…  ( 5 min )

    100 days of coding! Day 23
    June 25 2025 Today felt like one of those rare, fulfilling days where everything clicked, from hands-on coding to sharpening my problem-solving and diving into high-level architectural patterns. Here's a breakdown of everything I did and learned: 🧩 CRUD Operations with ASP.NET + REST APIs I exposed the functionality through RESTful APIs, covering: GET for retrieving all or specific data POST for adding new entries PUT for updating existing records DELETE for removing data It felt incredibly satisfying to see clean code turning into working HTTP endpoints. I especially enjoyed learning more about: Route mapping Model binding and validation Using DbContext to manage database calls Clean separation of logic with the repository pattern Usage of Dtos These hands-on experiences are making backend development feel more intuitive and powerful. I’m really starting to love working with ASP.NET. 🧠 DSA Practice: Completed the Arrays Section (Striver Sheet ✅) After getting back home, I shifted gears and jumped into some DSA practice. I’ve been following the Striver SDE Sheet, and I finally wrapped up the entire Arrays section today. Some of the problems I tackled included: Kadane’s Algorithm (Maximum Subarray) Move Zeros to End Rearranging Arrays Two-Pointer Techniques I can feel my problem-solving muscles getting stronger. It’s a long journey, but one problem at a time, I’m getting better. 📚 System Design Learnings: Rate Limiting & Microservices 🔄 Rate Limiting Token Bucket Algorithm Leaky Bucket Algorithm Fixed window vs sliding window counters These are crucial for protecting APIs against spam or denial-of-service attacks. It’s fascinating how something that seems simple can have multiple nuanced implementations depending on scale and architecture. 🧱 Microservices Architecture It gave me a high-level view of how real-world scalable systems are structured — something that books and YouTube lectures don’t always do justice to until you write it down and reflect. ✍️ Reflections Signing Off Anisha 💗  ( 4 min )

    How I Built a Real-Time News Feed for My Team Using apitube.io (And Why I Recommend It)
    Hey devs, I wanted to share a small side project that turned out way more useful than expected — and a tool that made it surprisingly easy: apitube.io. 🗞️ The Problem At my company, we needed a way to keep an eye on relevant industry news: Product launches by competitors Tech policy updates in key markets Mentions of our company in local press Sentiment around our brand and keywords We tried a few big-name news APIs, but they were either: Too limited in scope (mostly US/UK sources) Slow to update Expensive or rate-limited Weak on filtering or metadata 💡 The Solution: apitube.io I stumbled across apitube.io while looking for a multilingual, filter-heavy news API — and it was exactly what I needed. Key reasons I stuck with it: Covers 500K+ sources in 200+ countries, 60+ languages Super det…  ( 4 min )

    Technical Interviews in the AI Era
    Let’s be real, you don’t need more than 1 hour for a proper technical interview. The way most companies are doing interviews right now? It’s embarrassing.

    How to Create a Event Bus in Go
    In today’s landscape where microservices and distributed systems are prevalent, Event-Driven Architecture (EDA) plays a critical role. This architectural design allows services to communicate via events, either synchronously or asynchronously, instead of traditional direct interface calls. The event-based interaction mode promotes loose coupling between services and improves the system’s scalability. The publish-subscribe pattern is one way to implement event-driven architecture. It allows different components or services in the system to publish events, while other components or services can subscribe to these events and respond based on the event content. Most developers are likely familiar with this pattern; common technical implementations include message queues (MQ) and Redis’ publish…  ( 7 min )

    No one should have to learn about transaction isolation levels.
    Once upon a time, I was trying to fix a bug in a checkout system that would occasionally cause a limited item to be oversold. We didn’t have an appreciation yet for the wide world of race conditions so we started by just putting everything into a transaction. Transactions are good, right? We still oversold the last item sometimes. The core problem was a “check for absence before creating an entry” pattern. Transactions don’t solve this at all. We needed a locking system. Ruby on Rails had really good support for SELECT FOR UPDATE so we used that liberally and hoped for the best. We still oversold the last item sometimes. People got pretty upset, so after a year or two my boss told me it was time to actually fix it and I set aside a week to figure it out. Now, this process was complex enoug…  ( 4 min )

    How to truncate text in CSS (single and multi-line)
    Written by Chinedu Okere✏️ For years, developers have relied on hacky and hybrid approaches to truncating text on the Web. Most developers still consider using JavaScript for that and are unaware of the modern CSS text truncation solutions that don't require JavaScript. In this article, we’ll learn how to truncate text with three dots in CSS. We’ll use two reliable CSS text truncation techniques while covering single-line and multi-line truncations. Additionally, we’ll take some of these solutions a step further to implement practical use cases in front-end Web development. The only prerequisite for this tutorial is working knowledge of HTML and CSS. Knowing some JavaScript would be a plus for exploring practical use cases.

    Important topics in CSS
    Hello everyone! Welcome to my blog. Today we are going to explore some most important topics in CSS. 1. Box model: 2. CSS selectors: Class selector ID selector Element selector Combination selector, etc. 3. CSS position: Types of Position: Static Relative Absolute Fixed Sticky 4. Flex and Grid: When to use? When you're laying out items in a single direction (row or column). Ideal for navbars, menus, buttons, and simple alignment tasks. Grid: CSS Grid is a two-dimensional layout system — it lets you layout items in rows and columns at the same time. When to use? When your layout is complex (like a website layout with header, sidebar, main, footer). You want to control both rows and columns precisely. 5. Media query and Animation: Parts: @media – This tells the browser “Start a media query.” Media Type – Like screen, print, all. Most common is screen. Media Feature – Conditions like width, height, orientation, etc. Logical Operators – Use and, or, not to combine conditions. Animation: Animations let you change CSS properties over time — making your webpage look more dynamic or interactive. Required: animation-name – Refers to the @keyframes block. animation-duration – How long the animation takes (e.g. 2s, 1.5s). animation-timing-function – The speed curve (ease, linear, etc.). animation-delay – How long to wait before starting. animation-iteration-count – How many times to repeat (1, infinite). animation-direction – normal, reverse, alternate. That's it. When I am prepare for my interviews I found that these are the important topics in CSS. Moreover In my past two interviews they ask question in these topics as well. So I thought It would be great to share these with you.Thank you for reading this. I hope you like this. Will see you in my next blog  ( 4 min )

    📏 Feature Scaling in Machine Learning: Why It Matters and How to Do It
    In machine learning, every detail matters—including the scale of your data. Imagine you’re building a predictive model using features like age, salary, and distance traveled. If age ranges from 0 to 100 and salary ranges from 0 to 100,000, your model might disproportionately focus on salary simply because it has bigger numbers—not necessarily because it’s more important. That’s where feature scaling steps in. Feature scaling is the process of adjusting the range or distribution of features (columns) in your dataset so that they are on a comparable scale. In simpler terms, it’s like adjusting the volume of each column so that no one variable drowns out the others. ✅ Prevents model bias toward high-magnitude features ✅ Improves accuracy of distance-based models like KNN and SVM ✅ Speeds up o…  ( 5 min )

    I Design Digital Products. But I Forgot About the One That Mattered Most.
    As a developer and product strategist, I spend my days designing interfaces that reduce friction, improve retention, and keep users engaged. But when I looked at how my daughter interacted with digital tools — especially games labeled as “educational” — I saw the opposite: And worst of all? Parenting ≠ Black Box UX It hit me hard: I would never accept this UX in my own work. The problem isn’t screen time. It’s the absence of meaningful visibility into what’s happening inside the screen. I didn’t want to spy. I didn’t want full control. A UX Designed for the Parent-Child System Recently, I stumbled upon a platform that finally “gets it.” It was like having a UX audit of my child’s brain — in the best possible way.

    🧠 The Illusion of Thinking: Apple’s Deep Dive into AI’s Reasoning Limits
    Can AI really “think”? Apple’s new research suggests we may be mistaking verbosity for intelligence Large Language Models (LLMs) have evolved dramatically—from basic autocomplete machines to “reasoning” agents that can unravel math problems, write code, and simulate step-by-step logic. Enter Large Reasoning Models (LRMs)—variants like GPT-4o, Claude 3.7 Thinking, and DeepSeek-R1—that “think out loud” using long Chain-of-Thought (CoT) reasoning. These models are trained to produce detailed reasoning traces before arriving at an answer. Sounds like progress toward Artificial General Intelligence, right? Not so fast. Apple's research team conducted a systematic evaluation titled “The Illusion of Thinking”. The core idea? Move away from just evaluating final answers, and dive deep into the thi…  ( 5 min )

Let’s dive into the actual execution order of SQL queries and why understanding this can save you from common mistakes and boost your database skills.

    5 Essential Stages of Data Management Before You Start AI Projects
    My visit to the PSU Cybersecurity & Data Privacy Days 2 proved to be incredibly insightful.

To globally use custom fonts in an app, register them via the windowStage.loadContent callback in the onWindowStageCreate lifecycle of the EntryAbility.ets file. In scenarios like live broadcast rooms or feed streams, clicking a button opens a half-screen container with an RNView. Clicking within RN opens a new half-screen, allowing multiple half-screens to be stacked.

    Arc Browser is Dead, and Dia Isn’t the Answer: A deeply frustrated honest review

    ‘Total Recall' at 35: What One of Arnold Schwarzenegger's Best Movies Says About Its Star
    TL;DR: Total Recall turns 35, and it’s arguably Arnold Schwarzenegger’s breakout sci-fi opus—trading the buddy-comedy high of Twins for Paul Verhoeven’s gleefully brutal satire. Here, Arnie’s everyman Douglas Quaid is pitted against memory-implant conspiracies, blurred realities and a mutant-infested Mars, all while grappling with the classic Verhoeven duality of over-the-top, gruesome spectacle and sly social commentary. Beyond its killer one-liners and gooey special effects, the film quietly asks: is our hero the sum of his memories or his actions? Mars itself becomes a dystopian playground—far more plausible (and nastier) than any glossy billionaire fantasy—where corporate greed, radiation-mutants and human yearning collide in one of Schwarzenegger’s most surprisingly thoughtful action pieces.  ( 3 min )

Even though the rodent survived, the BBFC cut the scene from cinema, DVD and TV releases decades ago under animal-welfare laws—yet a streaming loophole let it slip onto Disney+ this April. The RSPCA blew the whistle on this gap in regulations, calling for the scene’s removal to protect both animals and viewers.

    Hidden Complexities of Scaling GraphQL Federation (And How to Fix Them)
    Federation gives teams the autonomy to move faster, but it also creates a web of hidden dependencies that are easy to overlook, often found in complex distributed systems. Schema changes can conflict without warning, ownership becomes harder to track, and the federation gateway, responsible for composing and deploying the supergraph, often becomes a single point of friction. Any issue in one subgraph can delay deploys for the entire graph. Platform teams are left responding to problems without the visibility or control to prevent them. Not every issue causes an outage. Sometimes a deploy gets held back because schema checks fail unexpectedly. At other times, a feature like a product details page returns null because a field was removed from another team’s subgraph.

    Using Wavelets and Clustering to Predict Odd or Even Numbers: An Overengineered Approach with Pretty (But Confusing) Plots
    Spoiler alert: If you just want to check parity, you only need to look at the last bit of a number's binary representation. But what if, just for fun, you tried to guess whether a number is odd or even by analyzing wavelet features extracted from its binary signal and clustering those features? Surprisingly, this quirky method achieves almost 70% accuracy — not bad for something completely unnecessary. Motivation Parity (odd/even) is one of the simplest integer properties, and can be computed directly with: y = n % 2 But what if we approached this simple problem using advanced signal processing techniques, just for the sake of exploration and learning? Idea: Convert numbers into binary bit signals, extract features at multiple resolutions using wavelets, cluster those features using uns…  ( 6 min )

Right out of the gate, I had a bad experience with Vercel. $40/month to have two engineers pushing code to the same repo that gets deployed to a shared vCPU somewhere...but we let it be for these past nine months while we shipped features. At some point though we knew we’d need to change this, since as an API company with a lot of ingest coming through, a per-request pricing model was never going to work for us in the long term.

    A programmer yelling at the clouds about vibe coding
    Vibe coding, noun Writing computer code in a somewhat careless fashion, with AI assistance Merriam Webster Vibe coding is all the rage these days, but is that really the way we want to go as an industry? I’m neither the first nor the second guy to buck the trend but maybe my viewpoint from someone at a testing startup THAT USES AI is interesting to someone. We all have heard the marketing spins of AI writing 25% of code at google, or replacing entire product departments, but in my personal experience these models are just not quite there yet to be let loose completely unchecked. I can (and regularly do) let AI write some tiny prototypes or auto-complete my mock-data in tests. But to me I regularly run into road blocks whenever I ask the AI to actually help me on a task I am struggling wi…  ( 5 min )

    Connect Your Agents to the MCP Server
    Let agents query, think, and act with real-time context. No frontend required. Recap So Far Day 1: Introduced the Model Context Protocol (MCP) and why it matters Day 2: Built the MCP Server that handles context for inference orchestration Until now, the frontend drove everything — it requested context from MCP and passed it to the agents. But what if your agents could manage themselves? What if they could fetch memory, update state, adapt roles, and operate without orchestration glue? That’s what today is about. In many LLM-based workflows, the frontend or coordinator acts as the brain. That works — but only to a point. As your systems grow more complex: Agents need autonomy They may trigger sub-agents They should be able to operate independently of a user interface…  ( 6 min )

    🧠 We Save Links, But We Don't Save Knowledge — Why I'm Rethinking Web Reading
    Every day, we scroll past dozens of articles, YouTube videos, newsletters, and GitHub repos. If we find something useful, we usually do one of two things: Bookmark it. Leave it open in a tab to "come back later". But let’s be honest — we rarely do. I started thinking: why do we save links in the first place? Usually, it's because: There’s a key idea we want to remember We want to use that content later in some form It feels too valuable to lose But links are just containers. The actual value lies in the content behind them — and more importantly, what we do with that content. Now that AI tools like ChatGPT can generate articles, summaries, and even posts on demand — are links even necessary? Yes, but with a twist. We don't just need raw content. We need: Contextual insight from real sources The ability to reformat and reuse what we read A way to act on that content (write, share, store, discuss) Saving links ≠ capturing knowledge. Imagine if: You paste a link and instantly get the summary + key points + shareable post You could tag or save the insight as part of a project You could ask: “Why does this matter?” and get a contextual answer You could repurpose the content into LinkedIn, Twitter, Notion, or Markdown in 1 click That's where my thinking is now. I'm working on experiments to: Extract reusable insight from web content Make reading more active, not passive Build an AI-powered link knowledge OS, not a bookmark manager But this isn’t about tools. It’s about a shift in how we extract value from what we read. Do you actually revisit links you save? What would make a reading → output workflow more useful? Are you using any system or tool that helps? I’m thinking aloud — would love to hear what others think.  ( 4 min )

    How I Built a Self-Correcting Prompt Generator with Multi-Stage LLM Calls"
    💬 I don’t really know Python. This post is about how I designed a self-correcting image prompt generator using a multi-stage LLM flow. Most LLM prompt systems work like this: You give it a caption It generates tags or scene descriptions You hope the structure makes sense But most of the time, it doesn’t. In a system like RΞNE — where consistency matters (we feed prompts to Stable Diffusion) — I didn’t want to manually audit outputs. So I built /genimgprompt: a self-checking, retry-capable multi-stage pipeline. We begin with caption + emotion + character + style_hint. The first stage uses a creative persona (RΞNE) to generate a vivid scene. Example input: { "caption": "A cyberpunk girl walks through a neon alley", "emotion": { "primary": "MYSTERIOUS", "intensity": 0.7 }, "character":…  ( 4 min )

    How to Get the Best Translation Quality from Machine Translation
    Many people ask how to get the best translation quality from machine translation (MT) without acknowledging the fact that machine translation quality cannot improve without human input. Machine translation will only yield you the best language translation that a computer alone can generate. This means that if you’re hoping for a machine translation application to autonomously generate high-quality translations of idiomatic phrases, local jargon and dialectical variations, you’re going to sabotage your translation projects. So, how to get the best translation quality from machine translation? Well, first we need to reinforce why you can’t get high-quality translation from machine translation software alone.

    SOLID SRP - 30 years later
    This is part 1 of a 5 part series, going through each of the principles in SOLID, how they have aged, and investigating if we can achieve a deeper more comprehensive understanding of what each principle is trying to achieve. To Uncle Bob's own words, SRP is commonly misunderstood to mean A module should do one thing and one thing only. In reality, SRP is meant as a corollary to Conway's law, which in simple terms state that software will naturally be segregated to mirror the topology of the teams building the software. Microservices is probably the most extreme example of this law. If you have one team dealing with user notifications and another dealing with user analytics you can bet that these two features will end up being split into separate services.

    How to automatically decrypt a LUKS LVM setup on boot with a USB
    This guide walks you through a robust procedure to auto-decrypt a LUKS-on-LVM setup at boot with a USB key. It assumes you already have your system set up with LUKS encryption on LVM. The core idea is simple: keep a dedicated USB stick at home to unlock your system effortlessly, and leave it behind whenever you head out, so your machine stays securely encrypted on the go. I extensively tested the procedure in multiple VMs and on real-world installs of Ubuntu 24.04 and Pop!_OS 22.04.

    Which AI is the strongest at writing code?
    Recently, I systematically tested the coding abilities of various models on a platform like ChatGOT that combines multiple AIs. Here are my test results: Claude 4 Sonnet is clearly leading in agent capabilities. When given clear requirements, it can write documentation, create tests, and write code. It can also debug, search for documentation, and correct code, continuously working for hours until all tests pass. In this aspect, Claude is unbeatable; GPT and the entire Gemini lineup cannot compete. When it comes to data structures and algorithms—essentially “hard intelligence”—the O3 series excels the most. Only O3 consistently provides optimal algorithms and architectural solutions. Claude often comes up with suboptimal algorithms. However, while it has fewer high-level errors, it tends to have a lot of low-level mistakes. Gemini’s hard intelligence is slightly weaker than O3 but considerably stronger than Claude 4. In terms of following instructions, Gemini is slightly better than GPT, and while it may be the most powerful overall, it is rarely utilized to its full potential. Most of the time, I use O3 as a professional architect and algorithm engineer to tackle the most challenging parts, while Claude acts as a junior programmer, gradually filling in various details and steadily working in the background. Gemini’s strong instruction comprehension and extensive knowledge, albeit with some hallucinations, are mostly useful in conversational modes.  ( 3 min )

    Where Are All the Perl Jobs in 2025?
    If you’re a Perl developer, you’ve probably heard it before: “Is Perl still a thing?” Let’s explore where the opportunities are today and how to find them. Despite not being the trendiest language, Perl continues to power core infrastructure in fields like: Finance – for transaction processing and batch scripting Bioinformatics – thanks to CPAN’s rich ecosystem System Administration – especially in legacy-rich environments Telecom & Hosting – for custom automation and reporting The reality is, companies with decades of code running in Perl aren’t eager to rip and replace something that still works flawlessly. One major shift in recent years is the rise of remote-first hiring. More companies are hiring global developers to work on existing Perl systems—whether it's maintaining codebases, modernizing legacy apps, or integrating Perl into cloud workflows. These roles aren’t always posted on major job boards. That’s why using niche platforms is key. General job boards often bury Perl listings under unrelated content or make it difficult to filter accurately. That’s why developers increasingly rely on specialized platforms like Perl-Jobs.com — a focused job board built specifically for the Perl community, offering remote, freelance, and full-time listings from companies that actually want your Perl skills. It saves time and connects you with opportunities that are actually relevant. Perl isn’t dead—it’s just not loud. There are still solid, high-paying roles out there for developers who know how to write clean, efficient Perl code. And with the right tools and platforms, you don’t have to hunt blindly to find them. So whether you're actively job hunting or just keeping an eye on the market, it’s a good time to dust off the resume and see where Perl can take you.  ( 4 min )
    Mastering Event-Driven Architecture: From Basics to Netflix-Scale Implementation 🚀
    ** What is Event-Driven Architecture? 🤔** Event-Driven Architecture (EDA) is a design pattern where application components communicate through the production and consumption of events. Instead of direct service-to-service calls, systems react to events that represent something meaningful that happened in the business domain. Think of it like a newspaper system - publishers write articles (events), and subscribers (readers) consume them when interested. The publisher doesn't need to know who's reading! Why EDA Matters in Modern Applications 💡 Traditional monolithic applications struggle with: Tight coupling between components Difficulty in scaling individual services Poor fault tolerance Hard to maintain and extend EDA solves these by providing: Loose Coupling: Services don't need to know…  ( 6 min )
    Unity Game Optimization for Low-End Devices
    Previously, I never really understood the phrase “runs on potatoes” back in 2016, until I had the scope to work with a Unity game development team and play a game that is developed with the Unity engine and works on a 1GB RAM Android phone. If you have mostly developed and tested on your dev machine or a flagship device, trust me, you are missing out on a very real part of the market that lives and breathes budget phones. 🔄 Stop Instantiating Everything If your game has bullets, enemies, or anything that comes and goes frequently—and you’re still using Instantiate() and Destroy() every time—you’re going to run into performance hiccups. What we did: Built a really basic object pooler. ## 🎨 Sprites + UI: Less Is Definitely More I once saw a junior dev make a mobile game with 4096x4096 textures. It looked stunning. It also ran at 9 FPS on our test phones. What worked for us: Keeping sprite atlases small and compressed (512x512 or 1024x1024 max). ## 💡 The Lighting Trap Baked lighting is your friend. Real-time lights? Not so much—especially with shadows. ⚠️ Garbage Collection: Silent Performance Killer The profiler became our go-to tool once we realized GC spikes were causing microstutters. The biggest culprits? ## 🧪 You Need to Test on Actual Crap Phones Seriously, when your only test device is an emulator or a Pixel 8, you are not serious about tackling issues that your game may encounter post-launch. ## 📌 Final Thought As a game developer, you should remember one thing that when developing a game, you need to make it run well for everyone, especially those not using a flagship phone, which is the real challenge. It is not about hacking your way to 60FPS. It is about understanding your audience and optimizing your game quality accordingly. When you are building games for low-end devices and want more tips and guidance to succeed in this industry, I would genuinely love to hear from you.  ( 4 min )
    Forget CSS Tricks and Complicated Design: Why Words and Images Actually Sell Your Landing Page
    During these last days I'm participating in discussions on a redesign of a landing page for an existing product. It may be perceived by many as an easy task, but it's not. The challenge lies in creating a landing page that not only looks good but also effectively communicates the value proposition of the product. It's very easy to be dragged into aesthetics, but they are not enough. The landing page must be easy to navigate and to read. It must use a language that is easy to understand and that speaks directly to the target audience. Additionally, the content must be clear, concise, and compelling. It must answer the question "What's in it for me?" and provide a clear call-to-action. The problem is way too often that we forget about the importance of words and images in selling our landing…  ( 5 min )

Grab your snacks and drinks, let's dive in! An Elegant Way to Sign Out Users When a user wants to switch accounts or leave your app, you can't just close it abruptly. Try this super useful signOut() method: import { auth } from '@kit/accountIdKit'; // Call this when the sign-out button is tapped It automatically clears the token and user information after sign-out. The Serious Business of Account Deletion ⚠️ This operation is like "deleting your account and running away," so make sure to have a confirmation step in your UI! Here's the core code: auth.deleteUser() User taps the "Delete Account" button. Re-authentication for Critical Moments When a user performs a sensitive action (like changing a payment password), the system might suddenly require them to sign in again. This is where you use reauthenticate: // Example with password verification Phone verification code Practical Pitfall Guide Don't panic when you run into issues. Try these common solutions: Q1: Why can I still get user info after calling signOut()? Check if there are multiple caches that haven't been cleared. Inform users in advance that their cloud data will be deleted. Check the network connection status. Provide clear error messages (don't just say "Operation failed"). A Heart-to-Heart Honestly, the most challenging part of the authentication module isn't the code, but handling all the edge cases. I recommend that you: Wrap sensitive operations in try-catch blocks.

Configure secret access through Dapr's Configuration resource: apiVersion: dapr.io/v1alpha1 kind: Configuration metadata: name: ecommerce-config spec: secrets: scopes: - storeName: azure-keyvault defaultAccess: deny allowedSecrets: ["payment-api-key", "shipping-webhook-secret"] - storeName: redis-secrets defaultAccess: allow deniedSecrets: ["admin-token"] allowedSecrets takes priority - only listed secrets are accessible deniedSecrets blocks specific secrets while allowing others Lists override the defaultAccess setting Whitelist approach (recommended for production): defaultAccess: deny allowedSecrets: ["service-specific-secrets"] Blacklist approach (good for development): defaultAccess: allow deniedSecrets: ["sensitive-admin-secrets"] This feature helps implement least-privilege access without changing your application code - just apply the configuration to your Dapr sidecar.  ( 3 min )
    Custom exception handling in Spring Boot
    Introduction One of the important tasks in creating an API is to return understandable error messages. Spring Boot already has a predefined error message format, but this format is not always acceptable and our application may require a custom format. In this tutorial, we'll configure Spring Boot's exception handling so that our backend application will respond with an error message in the following format: { "guid": "DCF70619-01D8-42a9-97DC-6005F205361A", "errorCode": "application-specific-error-code", "message": "Error message", "statusCode": 400, "statusName": "BAD_REQUEST", "path": "/some/path", "method": "POST", "timestamp": "2022-12-06" } Explanation of the format: guid — unique global identifier of the error, this field is useful for searching erro…  ( 5 min )
    Track NSE Derivatives Top Contracts Easily – Copy This Ready-to-Use Code
    Friends, after so many requests (literally bahut saare messages aaye the!), I'm finally back with another NSE-related Python tutorial.

    How to Index Pages Unindexed by Google Search - 2025
    Indexing the pages of a website is the number one step to ranking on its search result pages. So when you get a notification that some pages failed the crawl test, it puts you in a state of disarray and confusion. This solves the problem: Confirm domain ownership (easy peasy) either through G-tags or your GA4 account. Check the domain endpoint. Google rarely indexes endpoints that are critical. An example of a critical end point - sureway.com/dashboard. These type of pages must be excluded from being crawled by search engines using the Disallow rule in your robots.txt file. Ensure unindexed pages are internally linked to the primary domain. Irrelevant content. Only include relevant pages for index. Run technical audits on affected pages to fix broken links or other negatives like page speed. Should be <5s. Bonus Points: Sometimes all you have to do is literally do nothing and simply wait. Antithetical yes but does it work yes.  ( 3 min )

    Optional FDE in ubuntu using initrd hooks
    🔍 Context: Ubuntu’s Autoinstall (Subiquity) typically bakes full disk encryption directly into autoinstall.yaml, making it an all-or-nothing setup—either every install uses encryption, or none do. This becomes limiting when you want a single ISO image to support both encrypted and unencrypted installs without user interaction. In this blog, we will show how to use an initrd hook and a simple trigger mechanism to dynamically choose the right config at install time—enabling flexible, environment-aware deployments from a unified base image.

    🧨 Why PHP Is the Worst Programming Language on the Planet (And Somehow Still Alive)
    "If code is poetry, PHP is a ransom note made from magazine clippings." Once hailed as the duct tape of the web, PHP has powered millions of websites. Yet, in the year 2025, we must ask: how is this language still allowed near a server, let alone running half the internet? Let’s explore why PHP continues to earn its reputation as the most cursed survivor of the programming apocalypse. PHP's syntax is the software equivalent of a junk drawer. It has: $thisIsAVariable,` echo for printing, <?php embedded in HTML,` AND a function called create_function() that literally takes a string of PHP code and evals it. Want consistency?

    Superscalar vs SIMD vs Multicore: Understanding Modern CPU Parallelism
    For many years, improving CPU performance meant increasing clock speed → allowing more cycles per second. But today, we’ve reached practical limits in how fast we can push frequency due to power, heat, and physical constraints. As a result, modern CPU design focuses less on running faster and more on doing more per cycle. To achieve this, processors use three key architectural techniques: Superscalar execution SIMD (Single Instruction, Multiple Data) Multicore parallelism Together, these allow a CPU to complete multiple operations in a single clock cycle → making better use of each tick without increasing the clock rate itself. Before diving into these techniques, it’s important to understand CPU pipelining, the foundation of all modern CPU execution, which is covered in a separate article…  ( 5 min )

    Further Understanding Cargo and Crates.io
    In Rust, "release profiles" are predefined and customizable sets of settings with different options that allow programmers to control compilation options flexibly. Each profile is independent. Cargo mainly has two profiles: the dev profile used when running cargo build, and the release profile used when running cargo build --release. The dev profile is the default suitable for development, while the release profile is suitable for building optimized release binaries. You may see these names in the build output: $ cargo build Compiling cargo1 v0.1.0 (/rust/cargo1) Finished dev [unoptimized + debuginfo] target(s) in 0.67s $ cargo build --release Compiling cargo1 v0.1.0 (/rust/cargo1) Finished release [optimized] target(s) in 0.11s The output shows dev and release, indicating t…  ( 6 min )
    Proof Key for Code Exchange: A developer’s guide
    OAuth 2.0’s authorization code flow relies on a client secret to prove the client’s identity when exchanging an authorization code for tokens. But what happens when your “client” is a mobile app, a single-page app, or a CLI tool? (environments where you can’t safely store secrets) That’s where PKCE (Proof Key for Code Exchange) comes in. Originally added to OAuth 2.0 for mobile, PKCE is now mandatory in OAuth 2.1 for all public clients. It thwarts interception and replay attacks by binding each authorization code to a one-time secret. Public clients can’t hide secrets: Mobile apps and SPAs run on user-controlled devices or browsers: any embedded secret is extractable. Code interception is real: Without PKCE, an attacker on the same network or with a malicious browser extension could grab y…  ( 4 min )

    Hello everyone. Today, let’s summarize the data types in Cangjie. let arrayList1 = Array([1, 2, 3, 4, 5, 6]) //截取 arrayList1.slice(0, 1) //倒序 arrayList1.reverse() //查询 arrayList1.indexOf(1) Next comes the ArrayList type, which adds operations such as adding, inserting and deleting on the basis of Array: let arrayList2 = ArrayList([1, 2, 3, 4, 5, 6]) //在头部添加 arrayList2.prepend(0) //在尾部添加 arrayList2.append(7) //在指定位置添加 arrayList2.insert(2, 0) //删除元素 arrayList2.remove(1) Finally, there is the ObservedArrayList type, and correspondingly, there is also the ObservedArray type. They are typically used for state management. When the content of the array changes, they trigger the UI to update. let map = HashMap([('姓名','幽蓝'),('职业','码农')]) //修改 map['姓名'] = '123' //删除 map.remove('职业') //取值 map.get('姓名') //清空 map.clear() That’s all for today’s content.

    Understanding Feature Engineering: The Hidden Power Behind Data Science Success
    🧠 What is Feature Engineering in Data Science? Feature engineering is the process of transforming raw data into meaningful input for machine learning models. It involves selecting, modifying, or creating new features (columns or variables) from existing data to improve model performance. Think of it as teaching your model how to think better. Without good features, even the best algorithms will underperform. Even if you're using advanced models like XGBoost, Random Forest, or Deep Neural Networks, the quality of your input data (features) often has a bigger impact than the model itself. “Better data beats fancier algorithms.” — Peter Norvig (Google Research Director) Handling Missing Data Imputation: Fill missing values with mean, median, mode, or predictive models.

    Modelo de Maturidade Richardson (RMM)
    O Modelo de Maturidade de Richardson é uma estrutura proposta por Leonard Richardson para avaliar o quão "RESTful" uma API é, com base em sua aderência aos princípios do REST. Ele divide a maturidade em quatro níveis (0 a 3), cada um representando um grau crescente de conformidade com o estilo arquitetural REST. Abaixo está uma explicação clara e concisa de cada nível: Nível 0: The Swamp of POX (Pântano de POX) Descrição: APIs neste nível não seguem os princípios REST. Elas usam HTTP como um transporte simples, geralmente com um único endpoint e método (ex.: POST) para todas as operações, semelhante a chamadas remotas de procedimento (RPC). O termo "POX" significa "Plain Old XML", mas pode incluir JSON ou outros formatos. Características: Um único URI (ex.: /api) para todas as requis…  ( 5 min )

    The Art of Deception: Understanding Generative Adversarial Networks (GANs)
    Imagine two artists locked in a fierce competition. One, the generator, is a talented forger, striving to create incredibly realistic counterfeit masterpieces. The other, the discriminator, is a seasoned art expert, tasked with identifying the fakes. This constant battle of creation and critique is the essence of a Generative Adversarial Network (GAN). GANs are not about creating physical art, but rather, they are powerful machine learning models capable of generating remarkably realistic data – images, text, music, even code – that mimics real-world examples. At their core, GANs consist of two neural networks: the generator and the discriminator. They work in tandem, constantly improving each other through a process of adversarial training. Think of it as a never-ending game of cat and mo…  ( 7 min )
    Implementing a CDN in Your React App in 3 Simple Steps
    If your React app is feeling sluggish, overwhelmed by traffic, or just generally underperforming, the problem might not be your code itself, but rather how you're delivering it to your users. A CDN can provide a number of benefits to your React project: Faster Load Times: CDNs distribute your app's assets across multiple servers globally, ensuring that users receive content from the server closest to them, reducing latency. Global Reach in Seconds: Instantly deploy your app to a worldwide network of servers, making it accessible to users anywhere. Free HTTPS & Built-in Security: CDNs typically offer free SSL/TLS certificates and built-in security features to protect your app and users.

    Razões e Proporções
    📚 Aula de Matemática – Razão e Proporção 📏 1. Razão 🔎 O que é Razão? Razão é uma comparação entre dois valores, feita por meio de uma divisão. A razão entre os números a e b (com b ≠ 0) é dada por: Razão = a ÷ b = a : b A razão entre 10 e 2 é: 10 ÷ 2 = 5 → 10:2 = 5 Se em uma sala há 8 meninas e 12 meninos: Razão meninas:meninos = 8:12 = 2:3 (dividindo por 4) Proporção é a igualdade entre duas razões. Se: a/b = c/d dizemos que a, b, c e d estão em proporção. Se: a/b = c/d Então: a × d = b × c O produto dos extremos é igual ao produto dos meios. Verifique se 2, 3, 4 e 6 estão em proporção: 2/3 = 4/6 → 2 × 6 = 3 × 4 → 12 = 12 ✅ Proporção entre salários: João recebe R$ 2.000, Maria R$ 3.000 e Carlos R$ 5.000 A razão entre os salários é: 2000 : 3000 : 5000 = 2 : 3 : 5 Usamos proporções para resolver regra de três, onde comparamos duas grandezas. Exemplo: Se 4 lápis custam R$ 6, quanto custam 10 lápis? 4 --- 6 10 --- x → 4x = 6 × 10 → x = 60 ÷ 4 → x = 15 Resposta: R$ 15,00 Sempre simplifique as razões. Na proporção a/b = c/d, use a propriedade dos meios e extremos para resolver. Se a razão envolve unidades diferentes, transforme-as antes de calcular. (IFCE – adaptado) A razão entre dois números é 5:3. Se a soma deles é 64, quais são os números? Resolução: Chame os números de 5x e 3x (mantendo a proporção). 5x + 3x = 64 8x = 64 → x = 8 → Números: 5×8 = 40 e 3×8 = 24 ✅ Resposta: 40 e 24  ( 4 min )

    How to Install NVM on macOS
    Setting Up NVM on macOS (One-Time Setup) If you're a developer working with Node.js, managing multiple versions of Node across different projects can get messy. That's where NVM (Node Version Manager) comes in a handy tool that lets you easily install, switch, and manage multiple versions of Node.js. In this guide, we’ll walk you through a one-time setup of NVM on your macOS system. By default, macOS uses the Zsh shell, so we’ll work with that. Open the Terminal app. You can find it via Spotlight (Cmd + Space, then type Terminal). Make sure you're in your user’s home directory: List all files (including hidden ones) to check if .zshrc already exists: ls -a touch .zshrc This file is where you'll store shell configurations, including NVM-related settings. Use the official installation script from the NVM GitHub repository: https://github.com/nvm-sh/nvm curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.3/install.sh | bash Once installed, you need to reload your shell configuration so NVM is available in the terminal: source ~/.zshrc To confirm everything went smoothly, run: nvm --version  ( 3 min )

    Why API Integration Is Too Important to Leave to Non-Developers
    Let’s be honest—API integration is one of the most deceptively complex tasks in modern development. From the outside? Looks simple. Plug one system into another, pass some data, hit an endpoint. Done, right? In practice? Welcome to the wild world of mismatched schemas, brittle auth flows, unpredictable rate limits, and half-baked docs. That’s why it absolutely blows my mind when I see low-code platforms treating integration like a drag-and-drop form builder. Yes, visual tools are great—but pretending that non-developers can handle enterprise-grade integration without a hitch?

    Why Does AI Still Make Me Repeat Myself?
    After 24+ years of working with software delivery teams, through countless sprints, PRDs, vibe code sessions, and retro postmortems, one thing is abundantly clear: what slows us down isn’t the complexity of the product, it’s the SHEER REPETITION of how we build it. Where AI Currently Helps (and Fails) 1. PRDs to AI Prompt Convert PRDs into Code What’s repetitive: You already wrote the logic in the spec. Now you're just repeating it in a form GPT understands, without any context of the rest of the project. 2. Vibe Coding / Iterative Prompting Vibe Coding Fundamentals In 33 minutes What’s repetitive: Each change means another prompt. Want to add error handling? New prompt. Align with team’s standards? Another prompt. It's copy–paste, regenerate, repeat. 3. Manual Stitching and Fixing What’s repetitive: You debug structure misalignment, resolve missing references, rewire file paths—stuff that AI should’ve known if it had context. So… What’s the Real Problem? The Better Way: Automate the Setup You don’t write PRD-based prompts. You don’t vibe the same prompt five different ways. You don’t fix what AI didn’t know. Instead, your personal AI knows the spec, the screen context, the naming conventions and auto-builds the first working draft. All you need to do is the important stretch: enhance architecture, refactor for performance, and apply dev intuition where it actually matters. That’s the work that matters to developers. And that’s exactly what we built. Enter HuTouch: The Dev Repetition Killer Converts PRDs, UI designs, and code context to prototypes in one go Automatically integrates API using postman or 3rd party APIs Retains your coding standards for other tasks in the project Automates unit test creation, code review process Unleash your true potential and let HuTouch do the rest.

    🐲 Kth Smallest Product of Two Sorted Arrays – LeetCode 2040 (C++ | Python | JavaScript)
    Hi, Developers! 📊💥 Today, we tackle an advanced binary search problem — LeetCode 2040: Kth Smallest Product of Two Sorted Arrays. It combines elements of search space reduction, pairwise products, and the nuances of positive, negative, and zero multiplicands. Let’s unpack this elegantly and see how we can find the kth smallest product efficiently! You're given two sorted integer arrays nums1 and nums2, and an integer k. You must return the kth smallest product of the form nums1[i] * nums2[j], where: 0 <= i < nums1.length 0 <= j < nums2.length The arrays may contain negative values and zero A brute-force approach of generating and sorting all products would take O(N*M) time and space, which is too slow for arrays of size up to 5 * 10^4. Instead, we apply binary search on the product value…  ( 6 min )

    Google’s new AI will help researchers understand how our genes work

    Learning SQL for 30-days. Day 4.
    It's currently 02:53 AM, 06-25-2025. Today's learning begins late, it's literally tomorrow. I wouldn't call it learning per say, but it involves just me trying to write up some code based of what I have learnt in the past 2 days, with little to no guidance to see if I am understanding anything, haha. It's probably too soon for me to e doing that, but I still want to do it. 03:43 AM. Well damn, a girl is learning. Kudos to me. If I keep on moving like this I might just end up creating my own AI company, lol. I am going to start learning GIT and how everything works now, I will be doing it today and for the rest of the week maybe. There on I can maybe attach it on my profile and everywhere else, lol.

    PoC or MVP? The Choice That Can Make or Break Your Startup
    Every software product, from the simplest to the most complex AI-driven platform, starts with an idea. Maybe it struck you during a conversation, while reading a book, or in the middle of a frustrating work process that screamed for a better solution. But having an idea is not the hard part. Turning the idea into a functional and valuable product is where the challenge begins. In product development, two powerful approaches help innovators bring their vision to life. These approaches are Proof of Concept and the Minimum Viable Product. While both of these serve the larger goal of validating a product idea, they do so in different ways and at different stages of the development journey. Confusing between the two or choosing the wrong one can lead to wasted time, lost money, and missed opp…  ( 9 min )

    A couple of weeks ago I heard about AWS's Build Games Challenge, I got excited as I saw it as an opportunity to build my first game. At that time the challenge wasn't considering latin american countries, so I couldn't participate, but it was a pleasant surprise when I saw an update on the post where AWS was now accepting more countries, including mine, there were no more excuses for me. As the theme of the challenge was to build retro games, first I started to ask myself, what's "retro"? as for some people it could be a black and white, pixels only Pong game, and for others it could be N64 GoldenEye.

    Styling Your First React Component — A Gentle Introduction

    Programming Entry Level: basics syntax
    Understanding Basics Syntax for Beginners Have you ever tried to talk to someone who speaks a different language? It can be frustrating because you don't understand the rules they're using to communicate! Programming is similar. Computers don't understand English (or any human language) directly. They need instructions written in a specific syntax – a set of rules that tell the computer exactly what to do. Understanding basic syntax is the very first step to becoming a programmer, and it's something you'll be asked about in almost any programming interview. This post will break down the fundamentals in a way that's easy to grasp. Think of syntax like the grammar rules of a language. Just like English has rules about how to form sentences (subject-verb-object), programming languages have …  ( 6 min )

    Beyond the Hype: 16 Must-Have Resources for Navigating the XR and Metaverse Frontier

XR is an umbrella term encompassing Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR)—technologies that blend real and virtual worlds to create immersive experiences. The Metaverse, on the other hand, envisions a persistent, interconnected network of 3D virtual worlds where users can interact with each other, digital objects, and AI in real-time.

    Global by Design: Tigris's Distributed Object Storage Architecture
    At Tigris, globally replicated object storage is our thing. But why should you want your objects "globally replicated"? Today I'm gonna peel back the curtain and show you how Tigris keeps your objects exactly where you need them, when you need them, by default. Global replication matters because computers are ephemeral and there's a tradeoff between performance and reliability. But does there have to be? Storage devices can and will degrade over time. Your CPUs aren't immune from it either, recent Intel desktop CPUs have been known to start degrading and returning spontaneous errors in code that should work. Your datacenters could be hit by a meteor or a pipe could burst: being in the cloud doesn't mean perfect reliability. But failovers and multiple writes take precious time. We write yo…  ( 8 min )
    DynamoDB Streams with more than 24 hour retention
    That was kind of a misleading title, but I wanted to get your attention. The truth is that DynamoDB Streams have a maximum retention period of 24 hours and there is no way to extend that. When you do need more than 24 hours the default solution is to use Kinesis Data Streams, which can retain data for up to 365 days. While it would be easy to just move to Kinesis, this comes with extra cost which may not be justified for all use cases. At the time of writing this I actually am using Kinesis Data Streams for a project, but the only reason we are using it is because we need to retain data for more than 24 hours in case of a failure in the processing lambda. At the time this was built time was of the essence, and we needed a solution that would work out of the box. Kinesis Data Streams is a f…  ( 6 min )
    "Lifeforce" at 40 | A sci-fi horror film only Cannon could have made
    Lifeforce at 40: Cannon’s Glorious Train-Wreck Cannon Films, masters of low-budget sleaze turned surprise high-rollers, poured serious cash into Tobe Hooper’s space-horror epic Lifeforce. With a Bond/Jedi cinematographer, Henry Mancini’s lush score and VFX crews fresh from Star Wars and horror classics, it looks way more expensive than anything else in their catalogue—yet still oozes that cheeky Cannon exploitation vibe. The plot’s a deliciously bonkers mash-up: astronauts nab three seemingly dead humanoids (two guys and one very naked Mathilda May) from an alien ship masked by a comet, only for them to unleash life-draining “space vampires” on Earth. Peter Firth’s level-headed hero (and a briefly possessed Patrick Stewart) combat absurd logic twists, unapologetic nudity and hilarious one-liners. It’s equal parts stylish eye-candy, sleazy cult fun and so-bad-it’s-good “shitsome” brilliance.  ( 3 min )

    James Cameron's The Abyss Pulled From Disney+ in the UK Because of Banned 'Rat Abuse' Scene - IGN
    TL;DR: Disney+ UK quietly pulled James Cameron’s 1989 sci-fi classic The Abyss after spotting that a long-banned scene—where a real rat is dunked into a vat of fluorocarbon liquid—had snuck onto the April streaming upload. The British Board of Film Classification had outlawed the bit under 1937’s Cinematograph Films (Animals) Act and the 1984 Video Recordings Act, yet a loophole let it slip past because streaming services aren’t held to the same cut-it-or-lose-it rules as cinemas, DVDs or broadcast TV. Why it matters: The RSPCA slammed the “streaming loophole” that lets animal-cruelty footage play unchecked in our homes and called for consistent protections across all platforms. In response, Disney has yanked the movie until it can reinstate a version with that notorious rat scene removed—just like every other UK release.  ( 3 min )

    Tyler Perry sued by actor on ‘The Oval' for sexual assault and harassment
    TL;DR: Actor Derek Dixon—who’s appeared in 85 episodes of Tyler Perry’s BET drama The Oval—has filed a $260 million lawsuit in Los Angeles Superior Court, accusing Perry of using his industry clout to promise career opportunities in exchange for tolerating escalating sexual harassment, assault and professional retaliation. Dixon alleges Perry sent explicit texts (“What’s it going to take for you to have guiltless sex?”), threatened to kill off his character if he didn’t comply, and on multiple occasions forcibly groped him. Perry’s attorney calls the claims “completely fabricated” and vows to fight what they describe as a “shakedown.” The suit, first reported by TMZ, lays out screenshots of the alleged messages and details Dixon’s attempts to set boundaries while keeping his role—and hopes for a pilot deal—alive.  ( 3 min )

    Human Learning Is Dead—Long Live Human Meaning
    What Happens When Machines Lift the Weight for Us? Let’s kill the myth now: the version of “learning” that built saints out of suffering and heroes out of memory work is dead. The sacred pilgrimage through confusion and hardship—where friction itself was virtue—has been quietly, unceremoniously automated out of existence. Of course, the best teachers always knew that learning was more than pain or repetition; it was transformation. But for generations, the grind—whether memorizing Latin declensions or cramming for calculus—was the price of admission to knowledge. No more. Today, the burden is carried not by our minds, but by the machines we’ve built. The funeral was silent. The eulogy written by an algorithm.

    Permission Delegation: Unlocking a New Era of XRPL Account Management
    Introduction: What is Permission Delegation? The proposed Permission Delegation feature represents a significant upgrade in operational flexibility and security for token issuers, notably by enabling clear segregation of duties. It empowers issuers to delegate specific account actions or transaction types to other designated accounts without the need to share the primary issuer account’s keys. This allows specialized accounts to be authorized for their defined roles instead of being added to the issuer’s main Multi-Signature configuration where any rules are uniformly applied across all transactions regardless of business function.

    I Built My Own Programming Language and its Virtual Machine In Python!
    Ever looked at your code and wondered what really happens when you hit "run"? I mean, deep down, past the libraries and frameworks, how does your if statement actually... if? That curiosity bug bit me hard, and it led me down a rabbit hole that ended with me building my own programming language and virtual machine from scratch, using nothing but Python. I call it Pyle. So, Why Build a Whole Language? Pyle isn't here to compete with Python, JavaScript, or any of the giants. The world probably doesn't need another programming language from me (not to mention written in Python). But I needed to build one. I wanted to tear away the layers of abstraction and see the guts. How does text turn into something a computer understands? How does a + b actually work? Pyle is my personal la…  ( 6 min )
    A new passion; and a new project! A ThreeJS Physics Simulation
    I've been spending the last couple weeks in my spare time making a web based 3d skydiving simulation software utilizing ThreeJS designed to realistically visualize and simulate how a skydive unfolds from exit to canopy deployment. I had a couple of motivators starting this project - I recently returned to school to pursue a degree in Physics, but learning so much mathematical theory naturally inclined me to want to apply it to real world situations. After recently completing a skydiving training program, one thing became clear: there’s a serious lack of tools to help visualize where we are in the sky relative to other jumpers. Only after about 30 jumps do we gain the situational awareness to see where others are. I've designed this to help jumpers understand spatial awareness, separation, and freefall dynamics and how wind affects them in a more intuitive way before they even step foot on the plane. So far, the software includes A frame-by-frame time scrubber to review and analyze movement from any point Modular UI components that change the variables of the skydive A flexible camera system to observe from any position, or fixed to a jumper or plane Real weather data based on longitude and latitude (Pulled from Open-Mateo.com) Dynamic satellite imagery of chosen dropzone (Mapbox.com) Choose between 4 different planes with different flight characteristics (DC-9, Skyvan, Twin Otter, Cessna-172) This is just the beginning, but I hope that this passion project turns into something that can effectively assist others in preventing injury and accident in the sky.  ( 3 min )
    Pair Programming against Agentic Dementia
    Facing the challenges of AI-assisted development with a collaborative solution In my previous exploration of "agentic dementia," I outlined the hidden costs of our growing dependence on AI coding assistants—the erosion of learning, the subscription trap of cognitive outsourcing, the gradual loss of craft, and the knowledge lock-in that comes with AI-powered development tools. But identifying the problem is only half the battle. The question that keeps surfacing is: what's the alternative? If AI assistance comes with these cognitive costs, how do we maintain productivity while preserving our essential human capabilities? How do we harness the benefits of modern development tools without falling into the trap of intellectual dependency? The answer, I believe, lies not in rejecting technology…  ( 11 min )
    From Theory to Impact: Implementing Shift-Left from Scratch
    Shift-left, do you know what it is? After help my team implement this methodology from scratch, I've decided to write about what is the methodology, the benefits and practices that were essential for this methodology to work and improve not only the product we were working on, but our daily lives as QA and developers. Shift-left testing is an approach in software development that emphasizes moving testing activities earlier in the development process for improved software quality, better test coverage, continuous feedback and a faster time to market. This practice have a lot of benefits, like: Cost Savings: Early detection of defects through automated unit tests is cheaper than fixing issues that reach customer environments. Increased Efficiency: Continuous testing leads to quicker iss…  ( 7 min )
    If you’ve upgraded boto3 or the JavaScript S3 client in the last week, uploading files won’t work. Here’s how to fix it.

    Installing key components to kickstart a 20-day bootcamp for django
    CONNECT GITHUB WITH GITHUB SSH KEYS For this step, check for existing SSH Keys and I did that on ubuntu bash and wrote ls -al ~/.ssh. This lists the files in your .ssh directory. Looked for files like id_rsa.pub, id_ecdsa.pub, or id_ed25519.pub. They were not there so next is generating them. ssh-keygen -t ed25519 -C "youremail@gmail.com" your_email@example.com" with your GitHub email address. eval "$(ssh-agent -s) ssh-add ~/.ssh/id_ed25519 cat ~/.ssh/id_ed25519.pub ssh -T git@github.com At this point I feel like I am an expert because I know that docker is; a container, see expert. Headed to google typed in docker install windows because my laptop has windows 64 bits but what is the difference between ARM and AMG, food for thought. Run it, and either create a docker account or sign in via google or github, I used google easy. I installed Windows Subsytem for Linux by first installing ubuntu 24.0.0 via microsoft store, and it installed wsl by default, set up ubuntU and I had wsl. Prior to this bootcamp I had VS Code already installed and these were the steps I took. Then later into my learning journey I installed git. Basically same steps as I did with vs code only this time type git install windows, run it and now you have; git bash, git gui and some git documentation as well.  ( 4 min )

    🔒 My EC2 Instance Froze — No SSH, No Web CLI. Here's What Caused It (and How I Fixed It)
    Today I want to share something unexpected I faced — a stuck EC2 instance that wouldn’t respond to SSH or even the AWS Web CLI. It took me a while to figure out what was wrong, but I learned a lot through the process. If you’re new to AWS or DevOps like me, this might save you some stress! Everything seemed fine at first. But suddenly: I couldn’t SSH into my EC2 instance The Web CLI also wouldn’t connect The EC2 instance showed as “running” in the console Docker containers were running inside from the last few days At first, I thought it was just a temporary glitch. But even after stopping and starting the instance again, nothing worked. I was stuck. After digging deeper (and asking ChatGPT!), I learned that: My EC2 instance was a t2.micro, which uses CPU credits to manage performance. I h…  ( 4 min )
    Everything you need to know about referrals
    What exactly is a referral and why do companies use them? A current employee of a given company submits the resume of someone they know for an open role (or otherwise vouches for/endorses), which may improve the odds or speed at which their application is reviewed. In essence, the current employee is personally recommending this other person as a good fit for the company/role (though there are nuances). Yes, I think this is the part candidates are most likely to misunderstand! At some companies, especially larger ones, all referrals aren’t created equal. The referrer may have to share quite a bit of information about how they know the person they are recommending and/or sort the referral into one on of several categories. Common categories of questions on the referral form include: Refer…  ( 6 min )

    Job Searching: Interview preparation Tips
    Beyond the Application: Your Secret to Job Search Success The job search can feel like a relentless cycle of applying, with low response rates. Many spend all their time hitting Apply neglecting crucial interview preparation. But when that interview call finally comes, being unprepared can ruin your chances. The real key to landing a job? A smart balance between applying and preparing. Don't just repeat your resume. Instead, elevate it by elaborating on relevant experiences and skills. Decipher the job description like a roadmap, understanding not just current duties but where the role will evolve. Connect your skills to their needs, showing how you'll benefit the company, not just what you can do. And research like a pro – dive into the company's blogs, news, and even other job descriptions to grasp their priorities and culture. To truly optimize your job search, timebox your efforts. For general activity, aim for a 70/30 split: devote about 70% of your time to actively applying and networking, and a crucial 30% to proactive, ongoing interview preparation. This consistent prep includes practicing answers, refining your pitch, and brainstorming questions. Critical Exception: The moment an interview is scheduled, flip your focus immediately. Shift all available time to intensive preparation for that specific opportunity – research, tailor answers, practice, and conduct mock interviews. This is when all your proactive effort pays off. By strategically balancing your application efforts with consistent, deep preparation, and knowing when to go all-in, you'll transform your job search and significantly boost your chances of landing that dream role. Good luck. What other job search or interview prep strategies have worked wonders for you? Share your insights in the comments below!  ( 3 min )

    How to Effortlessly Clean and Manage Disk Space on Linux Servers with One Script
    Keeping a Linux server’s disk space healthy is a critical, yet often overlooked, sysadmin task. Over time, logs pile up, Docker storage balloons, and application caches accumulate — eating into your precious disk space and causing performance or stability issues. I recently faced this exact problem on a production server, so I wrote a comprehensive Bash cleanup script that automates the tedious investigation and cleanup tasks — saving hours and keeping my servers lean and performant. Here’s what commonly fills up disk space on Linux servers: Large and old log files in /var/log (including system logs and application logs like PM2’s) Systemd journal logs that grow indefinitely unless managed Docker storage layers and volumes that accumulate unused data Application cache folders (e.g., Node.j…  ( 5 min )

    Machine Learning Fundamentals: active learning example
    Active Learning Example: A Production-Grade Deep Dive 1. Introduction In Q3 2023, a critical fraud detection model at a major fintech client experienced a 15% drop in precision, leading to a surge in false positives and significant customer friction. Root cause analysis revealed a shift in fraudulent transaction patterns – a new attack vector exploiting a previously unseen feature combination. Retraining the model on the latest data helped, but the process took two weeks, requiring manual data labeling and a full model deployment cycle. This incident highlighted the limitations of purely passive model updates and the urgent need for a system capable of proactively identifying and learning from the most informative data points. This is where a robust “active learning example” implementati…  ( 7 min )

    # Axiom Bio Launches Liver Toxicity Dataset to Support AI Models
    Axiom Bio has released a comprehensive dataset of liver toxicity profiles for AI-based drug safety assessments. The dataset includes high‑content imaging data from human hepatocyte cultures exposed to around 130,000 compounds. Each compound is accompanied by multi-channel fluorescence microscopy images and annotated phenotypic readouts reflecting liver cell health  oai_citation:0‡techlifesci.com. Multi‑label classification data for hepatotoxic vs non‑toxic responses High‑resolution cellular images with quantifiable phenotypic features Standardized metadata for compound concentration, exposure time, and assay conditions Exportable formats including CSV and NumPy arrays for seamless integration Example Usage from axiombio import HepatoDataset data = HepatoDataset("axiom_livertox_130k") img, label = data[123] print(label, img.shape) The toolkit also includes helper methods for data normalization, visualization, stratified train/test splitting, and integration with deep learning frameworks like PyTorch and TensorFlow. Drug‑induced liver injury is a leading cause of clinical trial failure and post‑market drug withdrawal. By providing a large, annotated dataset, Axiom Bio enables AI models to learn from biologically realistic images, potentially improving early safety prediction and reducing late‑stage drug failure. Developers can fine‑tune convolutional neural networks or train explainable models to classify toxicity outcomes, perform transfer learning, or extract toxicity‑related features for downstream analyses. Axiom Bio is organizing a community challenge for AI teams to benchmark their toxicity prediction models. The dataset is currently available via the company’s portal, with academic access granted free of charge. Sources https://www.techlifesci.com/p/weekly-techbio-highlights-45-biotech  ( 3 min )

    My Take on OOP (Part 6): Forget "Polymorphism." It's Just Swapping Parts.
    I Like Feynman I'm a big fan of Richard Feynman. If you study physics, you usually end up reading his famous "Red Books," and from there, you get into his biographies. Feynman used to say, "If you can't explain something in simple terms, you don't understand it yourself." That's probably why he won a Nobel Prize for explaining theories with simple diagrams. Anyway, my point is, I don't get why people insist on explaining Object-Oriented Programming in such a ridiculously complicated way. I've been emphasizing that the biggest benefit of an interface is that it lets you define and enforce a contract in code. Another great benefit is polymorphism. I already explained this naturally when I talked about abstraction in the last part. If you just write up the contract, you don't have to care h…  ( 5 min )

Tools like Claude, Copilot, and Cursor are becoming more capable every month. They're not just suggesting completions - they're writing entire functions, refactoring files, and even running tests. As they do, the developer's role is fundamentally evolving. We're no longer just authors of code. We're becoming curators, reviewers, and gatekeepers of what gets shipped.

    In crypto and fintech, you're either moving at speed or you're irrelevant
    That one line from Jovi Overo, CEO of Vault, perfectly captures the brutal reality of building in Web3. As a developer deep in the trenches of smart contracts, chain integrations, and ever-evolving tokenomics, I’ve seen this truth play out over and over again. What you build today might be obsolete tomorrow — not because it’s bad tech, but because someone else shipped faster, integrated better, or caught a wave you missed. In his interview with CoinStats, Jovi shares insights that should be required reading for anyone building in crypto, especially devs. Vault is aiming to merge decentralized finance infrastructure with embedded finance tools — essentially letting Web2 and traditional platforms tap into crypto-native features without friction. This is a huge signal of where the industry is going: abstraction, interoperability, and developer-first tooling. Here are a few points from the interview that really stood out from a dev perspective: 1. Fintech x Web3 = Embedded Crypto 2. Speed Is Strategy — but UX Is Survival Optimized RPC strategies Account abstraction (ERC-4337 is your friend) ZK-powered identity and KYC Gasless transactions or pre-paid models Developers who master the backend and the user journey will define the next cycle. 3.

    Why More Developers Are Turning to Haskell in 2025
    In recent years, Haskell has transitioned from a niche academic language into a practical choice for production-level software. With its strong typing, purity, and expressive syntax, Haskell is becoming a serious contender for teams that prioritize code safety, maintainability, and long-term scalability. The Demand for Reliability As systems grow more complex and users expect near-perfect uptime, the cost of runtime bugs and unexpected behaviors has risen sharply. Haskell’s type system allows developers to catch many issues at compile time—often before they even hit production. This leads to cleaner, more predictable codebases. In 2025, development teams aren’t just chasing speed—they're chasing stability. Haskell provides exactly that. Functional Programming Goes Mainstream Functional pro…  ( 4 min )

    Supercharge VSCode GitHub Copilot using Instructions and Prompt Files
    Supercharge Your GitHub Copilot: How DevOps Engineers are Mastering Customisation Hey everyone! If you're a developer or, like me, a DevOps engineer, you've probably already experienced the magic that is GitHub Copilot. It's a game-changer, right? From suggesting boilerplate code to squashing annoying bugs, it feels like having an extra pair of hands (or rather, an extra brain) in your IDE. But here's the thing: out of the box, Copilot is fantastic, but it's also generic. It learns from billions of lines of public code, which is awesome, but it doesn't know your team's specific coding standards, your obscure internal libraries, or that quirky cloud configuration you spent weeks perfecting. And for us in DevOps, consistency, best practices, and domain-specific knowledge aren't just nice-t…  ( 10 min )
    I built a city explorer using the Strands Agents SDK
    Recently, AWS announced the release of Strands Agents, an open source SDK that takes a model-driven approach to building and running AI agents in just a few lines of code. A while ago I built a city explorer using Knowledge Bases for Amazon Bedrock so to experiment with Strands Agents, I built the same application, this time using Strands Agents. Here's the process I followed: I already have Python 3.13 installed in my local machine, if you don't already have Python 3.10 or higher installed be sure to download an install it. I have an AWS account so I enabled model access for Claude 3.7 in Amazon Bedrock in the same region as the default region specified in my code later. Claude 3.7 is the default model used by Strands Agents. I then proceeded to set up my environment as follows: # Create …  ( 4 min )
    Understanding Load Shedding
    Introduction In today’s digital landscape, applications must handle unpredictable traffic spikes without collapsing. Whether it’s a sudden surge in users or a distributed denial-of-service (DDoS) attack, systems need mechanisms to protect themselves from being overwhelmed. One such mechanism is load shedding, a defensive strategy that prioritizes critical functionality by selectively rejecting non-essential requests when the system is under stress. In this article, we’ll explore: What is load shedding, and why is it necessary? A practical demo that shows load shedding in action. By the end, you should understand how to apply this technique to keep your services resilient under pressure. Load shedding is the deliberate termination or deferral of non-critical requests to prevent system ove…  ( 5 min )
    [Share] Data-Driven Design: Leveraging Lessons from Game Development in Everyday Software
    Originally posted on Methodox Wiki: Data-Driven Design. Modern software often needs to adapt quickly - whether that means processing new data sets, adjusting to user preferences, or deploying new features safely without downtime. To achieve such flexibility, software engineers increasingly adopt a methodology known as Data-Driven Design (DDD). Originally popularized by game development, Data-Driven Design emerged prominently in the 1990s as large studios confronted a challenging problem: the need to iterate rapidly on complex and interactive content. Game developers realized it was costly and slow to rebuild and redeploy an entire game every time designers wanted to tweak gameplay mechanics, adjust character behaviors, or revise in-game dialogues.

    ⚙️ Tuesday Tech Tip: One Command That Changed My Workflow Forever
    Today's game-changer: git worktree (because context switching is expensive) You're deep in a feature branch, everything's messy, half-committed, and then: "Hey, can you quickly check that bug in main?" Your options: Stash everything, switch branches, lose your mental model Clone the repo again (and wait for node_modules to install... again) Commit incomplete work with "WIP: will fix later" All terrible. Git worktrees let you check out multiple branches simultaneously in separate directories: # Create a new worktree for hotfix git worktree add ../myproject-hotfix main # Now you have: # ~/myproject/ (your feature branch) # ~/myproject-hotfix/ (clean main branch) # Working on feature-xyz cd ~/myproject # Bug report comes in git worktree add ../myproject-hotfix main cd ../myproject-hotfix # Fix bug, commit, push git checkout -b hotfix/urgent-fix # ... fix and commit git push origin hotfix/urgent-fix # Back to feature work cd ~/myproject # Your half-finished work is exactly as you left it No context switching - your mental model stays intact No stashing - work in progress stays in progress Separate node_modules - no dependency conflicts Parallel development - review PRs while coding List all worktrees: git worktree list Clean up when done: git worktree remove ../myproject-hotfix Share .env files between worktrees: # In your main project ln -s ../myproject/.env .env I keep a dedicated worktree for code reviews: git worktree add ../myproject-review main Now I can review PRs without losing my place.

    What are knowledge graphs and why is everyone talking about them?
    How a decades-old idea became the connective tissue for today’s AI era Picture a customer-service AI agent that politely answers questions until a user asks something just outside its training data. Suddenly the bot stumbles, hallucinating facts or looping back to “I’m sorry, I don’t understand.” What’s missing is context, i.e. a structured memory of how the world is stitched together that the model can query, reason over and update as reality changes. That structured memory is exactly what a knowledge graph (KG) provides, and in 2025 every CTO evaluating an AI or data platform seems to have “knowledge graph” on the whiteboard. Blame (or thank) large-language models (LLMs): they’re great at generating fluent text from patterns, but they still need a source of truth to ground their answer…  ( 7 min )

    🇫🇷 From "Vingt et Un" to 21: Building a Lightning-Fast French Number Parser in Ruby
    Ever tried to parse French numbers in your Ruby application? If you've worked with French text data, you know the pain: "quatre-vingt-quatorze" should become 94, "trois millions deux cent mille" should transform to 3,200,000, but good luck finding a performant solution that handles all the linguistic quirks of French numbers! That's exactly the problem I set out to solve with StringToNumber, a high-performance Ruby gem that converts French written numbers into their numeric equivalents with blazing speed and bulletproof reliability. French numbers aren't just "difficult", they're linguistically fascinating and computationally challenging: Special cases: "quatre-vingts" (80) vs "quatre-vingt-un" (81) Compound forms: "soixante-dix" (literally "sixty-ten" = 70) Multiple formats: "vingt-et-un"…  ( 5 min )
    DAY 12-CSS SELECTORS
    Good Morning everyone! Today I learnt about different types of selectors in CSS. There are mainly three selectors and these are: 1.CLASS: We create this by writing the tag name followed by class="some name" in whichever element we want to target. We can use the same class name for multiple elements and an element can have multiple class names also. In CSS we access the class by writing .followed by class name. For eg in the below code: Hello World This is an example of class selector .title { background color:"pink"; In this the element which has the class name of title will have it's background color as pink. The same class name can be used for multiple elements and in that case all those elements will also have the same style …  ( 4 min )

    Today I learned about the Padavan succession, which is defined as follows: p[0] = 1 p[1] = 1 p[2] = 1 p[n] = p[n - 2] + p[n - 3] This is like the Fibonacci's succession, only misplaced. The last element is ignored, to be taken by the next computation. Let's implement this in Python: # Padawan (c) 2025 Baltasar MIT License def padawan_succ(n: int) -> list[int]: toret = [] if n > 0: match n: case 0: toret = [1] case 1: toret = [1, 1] case 2: toret = [1, 1, 1] case _: toret = padawan_succ(n - 1) toret += [toret[-2] + toret[-3]] ... return toret ... if __name__ == "__main__": print("Padavan succession") print(str.join(", ", (str(x) for x in padawan_succ(100)))) ... The output is: Padavan succession 1, 1, 1, 2, 2, 3, 4, 5, 7, 9, 12, 16, 21, 28, 37, 49, 65, 86, 114, 151, 200, 265, 351, 465, 616, 816, 1081, 1432, 1897, 2513, 3329, 4410, 5842, 7739, 10252, 13581, 17991, 23833, 31572, 41824, 55405, 73396, 97229, 128801, 170625, 226030, 299426, 396655, 525456, 696081, 922111, 1221537, 1618192, 2143648, ...

    AI vs. AGI: Key Differences and Why It Matters and What You Need to Know
    AI vs. AGI: What's the Big Deal? Ever wondered how your favourite social media app knows exactly what videos you'll love, or how your phone suggests the next word you type? That's Artificial Intelligence (AI) at work! But there's another, much more advanced type of AI that scientists and engineers are dreaming about: Artificial General Intelligence (AGI). Let's dive in and see what makes them different. Imagine a really clever calculator. It can do sums, complex equations, and even help with your maths homework, but that's all it does. That's a bit like Artificial Intelligence (AI). AI refers to computer systems designed to perform specific tasks that usually require human intelligence. Think of it as specialised smarts.

    Vibe Data Analysis: Natural Language-Driven Data Insights
    Introduction Vibe Data Analysis is an emerging paradigm in analytics where users instruct AI systems to perform data analysis using natural language instead of code or manual tools. In a Vibe-driven approach, you simply ask questions or gives high-level directives (the "vibe") and an AI powered by large language models (LLMs) handles the heavy lifting – from querying databases to generating charts and explanations. This concept shifts data analysis from a technical process to an intent-driven, conversational experience. In practical terms, Vibe Data Analysis is a conversational, AI-driven method of data analysis where users interact with data in plain language, and LLMs generate results, summaries, and visualizations in real time. The goal is to deliver fast, intuitive insights without r…  ( 31 min )
    Designing Incentives That Scale: How Broker Models Empower DeFi Platforms Beyond Tokenomics
    There’s a quiet shift happening in DeFi — and I think it’s long overdue. For years, we’ve relied on token incentives to bootstrap adoption. Yield farming, liquidity mining, governance rewards — they’ve worked well as initial traction models. But let’s be honest: they don’t scale forever. Inflation eats into sustainability, and users eventually chase the next higher APR. As someone deeply involved in DAO mechanics and product design, I’ve been thinking more about how DeFi protocols can create native revenue streams that are aligned with usage, not just funded by emissions. And one approach I believe is underutilized — yet full of potential — is the broker model. The Case Against Over-Reliance on Emissions Most DAO treasuries depend on token inflation. We incentivize liquidity with more toke…  ( 4 min )

    ⚡Supercharge Your Feature Flags Using OpenFeature + AWS Parameter Store
    A feature flag is a mechanism that allows specific functionality within an application to be enabled or disabled dynamically, without deploying new code. Feature flags play a pivotal role in modern DevOps practices by enabling teams to manage feature rollouts, control exposure to end users, and reduce risk during deployments. They are commonly used to disable incomplete or experimental features in production environments, enable gradual rollouts (such as canary or blue-green deployments), or restrict access to premium functionality based on user entitlements. For those of us working with AWS on a daily basis, AWS Systems Manager Parameter Store is a familiar and trusted service.

    API Product Management: Building Developer Tools That Developers Love
    APIs are the invisible infrastructure of the modern web. They power mobile apps, connect platforms, and fuel integrations. But building an API is not the same as building a product. If you’re in API product management, your users aren’t everyday consumers , they’re developers. And developers are the hardest audience to fake your way through. They’ll spot bad documentation, inconsistent behavior, or unclear error messages faster than you can say “stack trace.” So how do you build an API that developers don’t just tolerate, but love?

    The Quantum Paradox of Trust: Why We Will Rely on Computers That Are Built to Fail
    Imagine an engineer presents you with a new kind of engine. It is, they explain, unimaginably powerful, capable of solving problems that would take today's best engines billions of years. But there's a catch. Every single component within this engine—every gear, every piston, every wire—is fundamentally flawed. They vibrate uncontrollably, spontaneously break down, and forget their state millions of times per second. Would you trust this engine to power a city, discover a new medicine, or protect the world's financial secrets? This is not a hypothetical riddle; it is the central paradox of quantum computing.

    Umemura Farm Website – Devlog #15: Building the Contact Page: Day 1 Progress
    Today's Task: Building the Contact Form Today, I began working on the contact form for my site. The form is still incomplete, but I was able to set up the foundational structure. Started with Directory Cleanup Before even opening the actual contact page, I found myself reorganizing the project directories and file structure. That took longer than expected and, by the time I turned to the page itself, most of the day had already passed. Handling Header Differences Between Pages One issue I encountered was that the contact page header needed to behave slightly differently from the main page. On the homepage, the header uses an isScrolled prop to apply visual changes during scroll. This small difference required more time to implement than I anticipated. Layout Struggles: Logo and Background Alignment Even though I copied the same CSS settings for background size and logo positioning, subtle misalignments kept appearing. It took quite a bit of tweaking to make things line up properly across both pages. Small visual inconsistencies like this can be surprisingly time-consuming. Current Status By the end of the day, I had the basic layout for the contact page in place. The structure is there, but it’s not yet styled or functional. Next Steps Tomorrow, I’ll start filling in the necessary form elements and polish the design using Tailwind CSS. My goal is to keep the layout clean and accessible, with smooth transitions and consistent spacing. Date: June 24, 2025 tags: portfolio, webdev, tailwindcss, nextjs, uiux  ( 3 min )

    🚀 How Web3 Partnerships Like WhiteBIT 🤝 Juventus Are More Than Marketing
    In the past few years, crypto sponsorships in sports have often felt like surface-level marketing moves — logos on jerseys, halftime ads, quick NFT drops. And for developers in Web3, this matters more than it might first appear. At its core, this partnership signals that crypto companies no longer see marketing as an isolated vertical. Instead, they’re embedding product-driven engagement layers into their partnerships. That could mean enabling on-chain ticketing systems, NFT-based loyalty programs with real-world perks, or crypto payment options for merchandise and events. These aren’t speculative ideas anymore — they’re becoming practical integration points. From a developer’s perspective, the potential here is quietly massive.

    How I Used AWS CloudFront to Make My Site 2x Faster Globally
    There was a time when I thought a fast server meant a fast site. But I was wrong. No matter how optimized my code was, users from Europe or Asia were seeing slow load times. Meanwhile, everything loaded fine for me—because my server was in the same country. So I started digging. That’s when I found the real bottleneck: distance. The solution? AWS CloudFront.

    Why Next.js?
    How Next.js Got Big Next.js has rapidly become the go-to framework for building high-performance, SEO-friendly, React-based applications since its launch in 2016. Let me explain why and how it got so big in the web development scene now. Next.js stands out by offering multiple rendering modes in one framework: Server-Side-Rendering (SSR): Fresh HTML is generated on each request, ideal for dynamic content or personalized pages. Static Site Generation (SSG): Pages are pre-built at build time, perfect for blogs or documentation sites, and served fast via CDNs. Incremental Static Regeneration (ISR): Combines the best of SSR and SSG. Static pages refresh in the background without complete rebuilds. These capabilities give developers control over performance, scalability, and content freshness per page. SEO-ready: SSR/SSG ensures search engines crawl full-rendered HTML, improving indexability. Core Web Vitals: Features like image optimization, code-splitting, and Turbopack boost metrics like LCP, FCP, TTI. In real-world cases, many teams meet Google's Core Web Vitals thresholds on first deployment (89%) with Next.js VS 52% with other frameworks. With the image component, Next.js delivers: On-demand, responsive image Lazy Loading Modern formats like WebP CLS prevention Zero-config setup: File-based routing, type support, hot module reloading work out of the box. Full-stack in a single repo: API routes, SSR/SSG, and middleware all coexist. No need for separate backend codebases. Turbopack: Next-gen build tool (Rust-based) that dramatically accelerates builds, faster than Webpack and Vite. Next.js isn't just another React boilerplate. It is a full-featured, versatile application framework. Whether you are building a blog, e-commerce platform, marketing microsite, or full-stack application, Next.js delivers a powerful foundation, so you can focus on delivering value instead of wiring up infrastructure.  ( 3 min )
    How to Build Trust When Joining a New Team
    When you join a new team, it’s natural to want to prove yourself. But earning trust isn’t about delivering fast or showing off what you know—it’s about how you show up, listen, and slowly become part of the fabric of the team. At Loop, my first week was intentionally designed as a learning week. I was given a schedule packed with conversations across the org—engineers, PMs, even folks outside my direct team. No pressure to build, no assignments, just… listen, learn, connect. It’s a thoughtful setup that allows trust to build not through speed, but through presence. From there, trust came gradually.

    Stop Saying Democratize When You Mean Dumb Down
    Ever notice how every new tech tool promises to "democratize" something? Is making our tools simpler really a kind of liberation, or a new form of control?

    How I Built My First Recipe Explorer App Using JSON Server and JavaScript
    As a beginner in web development, I recently completed a fun and educational project — a Recipe Explorer App. This project helped me practice HTML, CSS, JavaScript, and learn how to use JSON Server to handle data like a real API. In this blog post, I’ll walk through how I built it and what I learned in the process. 🧱 Project Overview Viewing a list of recipes with their ingredients and instructions. Adding new recipes through a form. All recipe data is stored and managed using JSON Server, which simulates a RESTful API and makes front-end development feel like it’s connected to a real back end. 🧩 Tools and Technologies Used JavaScript – to handle logic and DOM manipulation. JSON Server – to simulate a database and API. VS Code – my development environment. Git & GitHub – for version control and backup. 🔄 Displaying Recipes Here’s a basic example of the code: javascript http://localhost:3000/recipes') function renderRecipe(recipe) { ${recipe.name} ; document.querySelector('#recipe-list').appendChild(recipeCard); ➕ Adding New Recipes Here’s how the add feature works: javascript fetch('http://localhost:3000/recipes', { 🤯 Lessons Learned JSON Server is a great tool for simulating real APIs during development. Building this app helped me understand the importance of separating logic into functions. Small projects like this are perfect for learning how front-end and back-end parts connect. 📌 Final Thoughts In the future, I’d love to expand this project by adding edit functionality or search filters — but for now, I’m proud of what I’ve built. If you’re a beginner like me, I highly recommend starting with a small project like this. You’ll learn a lot and have fun doing it! 🧠 Pro Tip bash 📚 References JSON Server GitHub  ( 4 min )

    How to Install DeepSeek Nano-VLLM Locally?
    Nano-vLLM is a stripped-down, no-fluff engine designed purely for blazing-fast offline inference with large language models. It’s lightweight (just ~1,200 lines of code) but packs a serious punch — featuring smart optimizations like prefix caching, tensor parallelism, CUDA graphs, and more. Whether you’re testing models locally or building a custom inference stack, Nano-vLLM gives you raw speed, full transparency, and zero dependency bloat. It mirrors the vLLM API for easy migration, while staying small enough to dive into and hack on. If you’re running models like Qwen3-0.6B on your own GPU or a cloud VM — this is your toolkit. Recommended: 1× RTX A6000 or higher for smooth performance with Qwen3-0.6B and above. Before jumping into Nano-vLLM, make sure your environment is ready: Python 3…  ( 8 min )
    JavaScript Variables Explained: let, const, and var
    JavaScript variables are one of the most fundamental concepts. They let you store, update, and use data throughout your code. In this post, you’ll learn what variables are, how to declare them, and the key differences between the types you’ll use. Before we get started, don’t forget to subscribe to my newsletter! Subscribe here! Now, let’s jump right into it! In JavaScript, variables are used to store data. They act as containers that can hold different types of data, like numbers, text, or even complex data. For example: let message = "Hello, world!"; Here, message is the variable, and "Hello, world!" is the value stored inside it. Check out Learnify — a simple, clean tutorial platform.

    How The Internet Works
    Our digital content, such as files, videos, and webpages, may be stored in data centers that are thousands of miles away or even on different continents. Due to the high latency introduced by bouncing data off satellites, data does not reach our devices via satellites, regardless of distance. The current internet would feel slow and unusable with that much delay. Subterranean and underwater fiber optic cables, which efficiently connect data centers to devices worldwide, are used by the internet instead. These cables carry data at the speed of light. Servers, which are specialized devices that house enormous volumes of data, including the videos and websites we visit on a daily basis, are located inside these data centers. The server's task is to find the content and get it ready for delive…  ( 5 min )
    Progressive Enhancement in 2025: Is It Still Relevant?
    Imagine this: Your shiny new web app looks flawless on Chrome—but crashes on a low-end Android browser. Now imagine your user just bounced, forever. Painful, right? In 2025, developers are obsessed with frameworks, edge computing, and AI-enhanced UIs. Yet Progressive Enhancement—the old-school approach—might be the unsung hero your product still needs. Here’s why it matters more than ever today 👇 At its core, Progressive Enhancement is a strategy that starts with basic, accessible content and functionality, then adds advanced features for browsers that can handle them. Think of it like this: "Start with a reliable bicycle. Add a motor later if you can—but the bike should still ride perfectly." ✅ Ensures accessibility Even though we're building ultra-fast SPAs and AI-powered apps, the rea…  ( 4 min )
    The standard - S3 IAM Policies
    In the previous post, we explored S3 Access Control Lists (ACLs) proper way of securing your S3 buckets: Unlike ACLs, which are considered legacy and can become operationally chaotic, Today we'll focus on IAM policies - the backbone of AWS access control that actually makes sense. Before we dive deep, let's clarify the two main policy types for S3: IAM Policies are attached to IAM users, groups, or roles and define what actions Bucket Policies are attached directly to S3 buckets and define who can Both use the same JSON policy language, but they serve different purposes IAM policies follow a standardized JSON structure that's both powerful and { "Version": "2012-10-17", "Statement": [ { "Sid": "AllowS3ReadAccess", "Effect": "Allow", "Action": [ "s3:GetObje…  ( 7 min )
    Lexus LFR Spied Testing: GR GT3's Street-Legal Evolution Nears Debut
    Three years after Toyota's GR GT3 concept previewed a future halo car, its road-going counterpart – likely badged as the Lexus LFR – has been spotted testing aggressively in California. Veteran journalist Jonny Lieberman captured camouflaged prototypes on Angeles Crest Highway, revealing critical new details: Design & Stance: Even under wrap, the LFR's low-slung, wide-profile exudes purpose. Notably, the massive rear wing seen on earlier prototypes is absent, hinting at potential variants: A base model focused on street refinement.

    Resiliency Patterns
    Core Resiliency Patterns 1. Retry Pattern Uses a "retryForever" policy with constant backoff Configured with 5-second intervals between retries Set to unlimited retries (maxRetries: -1) to handle transient failures Applied automatically when component operations fail 2. Circuit Breaker Pattern Implements a "simpleCB" circuit breaker with three states: closed, open, and half-open Trip condition: Opens after 5 consecutive failures Timeout: Remains open for 5 seconds before transitioning to half-open Test requests: Allows 1 request in half-open state to test if service has recovered Recovery: Closes circuit if test request succeeds, reopens if it fails The resiliency patterns are defined in a YAML specification that includes: Policies section: Defines retry and circuit breaker behaviors Targets section: Specifies which components (like the statestore) the policies apply to Scoping: Applied to specific Dapr applications through the scopes field Normal operation: Application continuously saves and retrieves state via Dapr APIs Fault introduction: When the backing service (Redis) becomes unavailable, requests begin failing Retry activation: Failed requests trigger the retry policy with constant 5-second intervals Circuit breaker engagement: After 5 consecutive retry failures, the circuit breaker opens and halts requests Recovery testing: Circuit breaker periodically switches to half-open to test service availability Automatic recovery: Once the backing service is restored, the application seamlessly resumes normal operation This demonstrates how Dapr's resiliency features provide automatic fault tolerance for service-to-component interactions without requiring application code changes.  ( 3 min )

    Will AI Replace Frontend Developers? Here’s My Take
    "Will AI replace frontend developers?" I've been asked this at least 17 times in the last month. And honestly, I'm tired of the fear-mongering. Let me save you the suspense: no, AI won't completely replace frontend developers. But it will absolutely transform how we work. The relationship between AI and frontend development isn't a death match – it's more like an awkward dance where both partners are still learning the steps. I've spent years watching this evolve, and the truth about AI in frontend development is far more nuanced than most hot takes suggest.

    What is an MVP in Agile development?
    In 2025, MVP in Agile has become a buzzword among founders. Whether you're building your first startup or contributing to your 20th sprint, you've probably heard the term MVP thrown around in Agile standups and planning meetings. But what exactly is an MVP in Agile development? Let’s clear it up — and truly understand what an MVP is. What is MVP? An MVP (Minimum Viable Product) is the most basic version of your product that solves a core problem for the user and can be delivered quickly to validate an idea. In simpler words: It’s the smallest thing you can build that delivers value to your users and lets you learn something real. In Agile, this fits perfectly into the philosophy of "build fast, learn fast." Why MVP Matters in Agile Agile development is all about iterative progress — bu…  ( 4 min )

    I Created a Simple Tool to Instantly Preview HTML Generated by ChatGPT
    Introduction ChatGPT has become a powerful ally for generating HTML and other code snippets. However, if you’ve ever tried working with the HTML code it outputs, you might have run into a small but persistent annoyance. To preview the HTML, we typically need to: ・Manually create an .html file This process may not be complex, but doing it repeatedly can become surprisingly tedious. To reduce that friction, I created a small web tool that lets you paste HTML code and instantly render it in the browser—without saving any files. 🔗 Try it here Copy the HTML code generated by ChatGPT Paste it into the input field on the tool’s page Click the “Render” button That’s it. The entire page will be temporarily replaced with your HTML content. No need to create or save any files manually. This tool uses document.write() to replace the document with your input. If your code contains syntax errors, the browser will usually provide helpful messages, and the line numbers in the console log remain consistent with your input. This makes debugging a bit easier as well. Opening and saving HTML files manually each time you want to make a change might seem trivial at first. But over time, it adds up and slows you down—like a slow-draining battery. With this tool, I hope to make your workflow just a little more efficient and enjoyable. It's available on GitHub, so I'd be happy if you could download it and place it on your desktop. Thank you for reading, and happy coding!  ( 4 min )

    Over the past decade, we've witnessed the explosive rise of both blockchain and artificial intelligence. Yet as we bring these two forces side by side, a glaring gap becomes evident: Why Rebuild the Operating System for an AI-Native World? Smart contracts don’t initiate actions. Protocols don’t sense their environments. Blockchain systems don’t learn or evolve. In contrast, AI systems are inherently proactive: They operate continuously. They adapt through feedback. They evolve based on context. These two worldviews are structurally incompatible. You can’t encode intent-driven intelligence in if-else logic. You can’t build autonomous systems on top of stateless, call-and-return contracts. And you can’t expect systems built for finance to serve the needs of intelligent agents. Web3 infrastru…  ( 5 min )

Durante semanas —o meses— vivimos un boom: la gente usaba IA para todo, desde escribir correos hasta generar imágenes o resolver tareas. Pero ese primer impulso fue solo el principio. A partir de 2024, algo cambió. Ya no se trataba solo de experimentar. Las herramientas empezaron a madurar, integrarse y escalar. Hoy, prácticamente cada se…  ( 5 min )
    Stop Switching Tabs. Start Using AI Like You Mean It
    Right now, you probably have at least fifteen browser tabs open. Maybe twenty. One for your email, another for that document you're supposed to review, three more for research you started but never finished, and countless others for tasks you've forgotten you even began. Sound familiar? You're not alone. The average knowledge worker switches between applications and browser tabs over 1,100 times per day. That's once every 40 seconds during an 8-hour workday. But here's the kicker: each switch costs you approximately 23 minutes of focused attention time. Welcome to the productivity paradox of our digital age—we have more tools than ever before, yet we're less productive than we've been in decades. The solution isn't another productivity app or browser extension. It's fundamentally changing …  ( 10 min )
    Introducing My Python Selenium Framework: A Solid Foundation for UI Testing
    Let's be honest: UI test automation can feel like herding cats. You write a test, it passes. You run it again, it fails. You run it a third time, and it passes—just to keep you guessing. If you've ever wanted to throw your laptop out the window after a flaky test run, you're not alone. (Don't worry, your secret's safe with me.) After years of wrestling with this chaos, I decided to build something that would bring order to the madness—a UI test automation framework that's not just reliable, but actually fun to use. (Yes, really!) Today, I'm excited to introduce this open-source framework, built with Python, Selenium, and Pytest. It's like a Swiss Army knife for UI testing, minus the risk of poking yourself. This post kicks off a series where I'll dissect every part of this framework, shari…  ( 6 min )

    Power BI: DAX Functions, Power Query Editor and Dashboards
    Power BI is a powerful business intelligence tool that allows users to analyze, visualize, and share data insights in an interactive and user-friendly way. After learning how to use Power BI, I have discovered how effective it is in transforming raw data into meaningful reports and dashboards. One of the key features of Power BI is the ability to clean and prepare data efficiently. I can easily change data types, replace incorrect values, and handle missing values within the Power Query editor, ensuring the dataset is accurate and ready for analysis. In addition to cleaning data, Power BI allows the creation of new columns, measures, and even entirely new tables using DAX (Data Analysis Expressions) functions. DAX is a formula language designed for creating powerful calculations. With DAX, I can perform complex calculations like cumulative totals, conditional logic (similar to Excel's IF statements), and advanced aggregations to generate deeper insights. This makes it possible to create custom KPIs, ratios, and performance metrics that go beyond the standard summaries. Finally, building relationships between different tables is central to working with Power BI. The tool supports various types of relationships such as one-to-one, one-to-many, and many-to-one, which helps link different datasets together to create a comprehensive data model. Once the model is set, I can bring my analysis to life using interactive visuals like cards to display key figures, bar charts to compare performance, and slicers to filter data in real-time. Power BI has truly made it easier to explore data, spot trends, and communicate insights clearly and effectively.  ( 3 min )

    Implementing "Suspense" with a simple Observable
    Some frameworks tend to overcomplicate stuff that's otherwise trivial. We want to render some text whilst another process is pending, then display the results. Some people call this "Suspense". We can implement it as a simple stream that emits a placeholder initially and the final result when it's available. A BehaviorSubject from rxjs is all you need to get started. import { BehaviorSubject, switchMap } from 'rxjs'; import { rml } from 'rimmel'; const getData = () => fetch('/api').then(r=>r.text()); const suspended = new BehaviorSubject('Loading...').pipe( switchMap(data) ); document.body.innerHTML = rml` ${suspended} `; Try it yourself on Stackblitz So, why should you use this, instead of the alternatives? You could use Angular, but you'd have to convert this to a Signal. You could use React, but you'd need some adapter library such as react-rxjs. You could use Vue.js, but there you have to subscribe to the stream, update a signal and use that. Also, with most of these you'll have to manually unsubscribe from your streams to avoid memory leaks and clean up after yourself. Rimmel.js is the only UI library that makes it possible to use reactive streams directly in your templates, simplifying UI development considerably. It also simplifies the use of Observables, traditionally considered a particularly challenging endeavour. If RxJS is the best library for reactive streams, Rimmel is the best UI library for RxJS. Try it out now for a totally new development experience.  ( 3 min )

    The URL Space is Bigger than the Universe
    For the past few years I’ve been trying to build an operating system that can do everything you expect an operating system to do while also encoding its entire state as a single URL. That way, we get a permanent link to every O/S state, achieving truly comprehensive deep linking. For a long time, I struggled with finding a solid approach to achieving this goal. A user-friendly operating system involves many independent, dependent and otherwise tightly-coupled components — especially when you want it to be a platform that supports third-party app development. I tried a variety of different methods to encode/decode data from a string without redundancy. Some of my attempts involved query parameters, some of them base64-encoded JSON data, and some of them custom domain-specific languages. The…  ( 9 min )

    Build a local chatbot with React, openAI, and indexed DB (using Dexie.js)
    Everybody wants to use AI, and I'm sure many clients will ask you to integrate a chat or agent into their products. Quick overview With the rise of large language models (LLMs) like OpenAI, Gemini, and DeepSeek, many companies are looking to integrate chatbots into their apps not just as support tools, but as intelligent advisors or agents. These chatbots can offer personalized, value-added services by giving the LLM context from the app itself, making conversations more relevant and useful to the user. In this post, we will create a chatbot using React and IndexedDB. We will use a wrapper called Dexie.js to help us implement our local database for storing information persistently.. However, before we proceed, we need to understand what IndexedDB is. IndexedDB db is basically a low-level d…  ( 8 min )

    Medical RAG Research with txtai
    txtai is an all-in-one AI framework for semantic search, LLM orchestration and language model workflows. Large Language Models (LLMs) have captured the public's attention with their impressive capabilities. The Generative AI era has reached a fever pitch with some predicting the coming rise of superintelligence. LLMs are far from perfect though and we're still a ways away from true AI. One big challenge is with hallucinations. Hallucinations is the term for when an LLM generates output that is factually incorrect. The alarming part of this is that on a cursory glance, it actually sounds like factual content. The default behavior of LLMs is to produce plausible answers even when no plausible answer exists. LLMs are not great at saying I don't know. Retrieval Augmented Generation (RAG) helps…  ( 11 min )

O Vsauce fala sobre absolutamente qualquer assunto, mas, acima de tudo, ele me ajudou a recuperar a curiosidade de entender o “porquê” das coisas. Conforme a gente vai ficando mais velho, muitas vezes paramos de questionar o mundo ao nosso redor. Mas o Vsauce não.

    Declarative Programming: SQL, HTML, CSS, Prolog Guide
    Welcome, fellow developers and curious minds! Have you ever wondered why some code feels like a detailed instruction manual, while other code feels more like a concise wish list? That's the core difference between imperative and declarative programming paradigms. In this article, we're diving deep into the world of declarative programming, exploring its power, elegance, and how it shapes some of the most fundamental tools we use daily, like SQL, HTML, CSS, and even the fascinating logic of Prolog. At its heart, declarative programming is about "what to do," not "how to do it." Imagine telling a chef you want a "delicious chocolate cake" instead of giving them step-by-step instructions on mixing ingredients, preheating the oven, and baking times.

    大規模なスタイルセットを記述する場合、CSS では限界があります。そこで登場するのが、CSS プリプロセッサ と呼ばれるツールです。その中でも代表的なのが SCSS (サス、Sassy CSS) です。 SCSS は CSS をより効率的かつ構造的に書くための拡張言語です。SCSS コードは、CSS に変換可能であり、実行時には CSS としてブラウザに解釈されます。 メリット SCSS 記法 メリット 変数 $primary-color: #007bff; 一括変更、管理のしやすさ ネスト .parent { .child { ... } } コードの可読性、構造の把握が容易 ミックスイン @mixin my-btn { ... } スタイルの再利用、記述量の削減 インポート @import 'variables'; ファイル分割、管理のしやすさ 変数: 色やフォントサイズなど、繰り返し使う値を定義して管理できます。変更があった際に一箇所修正するだけで済むため、メンテナンスが容易です。 ネスト: CSS セレクタを入れ子 (ネスト) にして書くことができ、HTML の構造を反映した、より読みやすいコードにできます。 ミックスイン: 繰り返し使う CSS のまとまりを関数のように定義し、必要な場所で呼び出して使えます。ベンダープレフィックスの管理などにも役立ちます。 インポート: CSS ファイルを分割して管理し、必要な場所でまとめて読み込むことができます。 $primary-color: #007bff; $font-size-base: 16px; .header { background-color: #f8f9fa; padding: 20px; h1 { color: $primary-color; // 変数を使った計算も可能 font-size: $font-size-base * 1.5; } nav { ul { list-style: none; padding: 0; li { display: inline-block; margin-right: 15px; a { color: #333; text-decoration: none; // & で親セレクタを参照 &:hover { // 色を暗くする関数 color: darken($primary-color, 10%); } } } } } } @mixin button-style($bg-color, $text-color: white) { background-color: $bg-color; color: $text-color; padding: 10px 20px; border: none; border-radius: 5px; cursor: pointer; } .primary-button { // ミックスインを呼び出す @include button-style($primary-color); } .secondary-button { @include button-style(#6c757d); } Vue プロジェクトで SCSS を使うには、SCSS をコンパイルするためのローダー (sass 等) をインストールする必要があります。 npm install -D sass そして Vue コンポーネントの タグに lang="scss" を追加します。 // ここに SCSS を記述 .my-component { h2 { color: blue; } } SCSS を導入することで、CSS によるスタイル定義を構造的に整理できるようになります。それによって大規模アプリでもスタイリングの管理がしやすくなります。  ( 4 min )
    Text Compressing Introduction - Huffman Coding in Swift
    Text Compression for Beginners: Building Huffman Coding from Scratch in Swift Ever wondered how file compression actually works? This weekend, curiosity got the better of me, so I decided to dive deep and implement Huffman coding from scratch. 🌳 How Huffman trees work (with visual examples) 📊 Why Huffman is perfect for text/code compression 🔍 Step-by-step walkthrough of the "Mississippi" example ⚡ How to achieve ~50% compression on typical text files Unlike Run Length Encoding (great for images), Huffman coding shines with the kind of files we work with daily - source code, JSON, XML, plain text. It assigns shorter bit sequences to frequent characters and longer ones to rare characters. The best part? It's lossless - your original file is perfectly restored after decompression. A complete compression/decompression system including: Frequency analysis Huffman tree construction Bit-level file operations Compact tree serialization Ready to see how "Mississippi" becomes just 3 bytes? Let's dive in! 👇 Continue reading on my blog → P.S. The CLI tool is called "Kompressor" after my vacuum-packed cat plushie that never fully "decompressed" 😸  ( 3 min )

    DevOps как по учебнику. Возможно ли? [RU]
    DevOps — это не отдельная роль, а скорее философия или набор практик, принятых внутри компании/команды. За свой опыт я успел побывать, наверное, во всех вариантах «DevOps»: и как отдельный инженер, жёстко привязанный к команде разработки, и как инженер, Прежде чем поговорить о том, как проводить культурные изменения и нести в команду практики, призванные размыть границы между DevOps и разработкой, Это структура, к которой применимо описание «сисадмины на стероидах». Отдельная организационная единица, «Опять этой разработке что-то надо». «А давайте отполируем вот это решение, хоть оно и не несёт business value». «Давайте переизобретём свой костыль!» (чистейший NIH-синдром — Not Invented Here).

    Stop Duct-Taping Context Into Prompts: Meet the MCP Server
    Learn how the Model Context Protocol (MCP) can power smarter, scalable, and stateless AI agent systems. If you’ve ever built anything slightly more complex than a simple chat interface with an LLM, you’ve probably run into the same wall most of us hit: Agents forget things. Context doesn’t persist. Coordination feels clunky. Everything breaks when scale enters. Welcome to the context crisis. The era of building LLM-powered tools and agents is here — but our infrastructure isn’t ready. Most devs are duct-taping memory, state, and agent logic into isolated silos, and calling it a day. But you know that won’t scale. What if you could separate the logic of what a system should do from what it knows and how it remembers? That’s where the Model Context Protocol (MCP) comes in — and no, this is…  ( 6 min )

    Databases Are the Next AI Frontier
    Author: Tobie Morgan Hitchcock This blog post was inspired by Kolawole Samuel Adebayo's Forbes article on The AI Race Is Now About Databases — Not Just Big Models. The article is insightful to highlight that AI’s bottleneck is no longer compute, it’s about databases: data, storage, and memory. The last few weeks made that shift visible in capital letters, with multiple database acquisitions in the AI space. These aren’t just tech M&A headlines. They’re a collective admission: to scale AI, you first have to rethink how memory (not only data) is managed. The frontier has moved down-stack. It’s no longer just about building bigger models or fine-tuning LLMs. It’s about how agents access, reason over, and persist context in real time.

    Singleton with IIFE for state management in JavaScript
    Ever needed a centralized configuration manager in your JavaScript app? 🤔 In modern JavaScript apps, managing shared state or configuration often means reaching for heavy tools like Redux, Zustand, or context APIs. But what if you're working on a small utility, a framework-agnostic widget, or just need a simple global config? This is where the Singleton pattern with an IIFE (Immediately Invoked Function Expression) comes in handy. It offers a lightweight, zero-dependency way to encapsulate state, avoid global pollution, and keep things clean—all without introducing a full-blown state manager. const configManager = (() => { let config = {}; return { set(key, value) { config[key] = value; }, get(key) { return key ? config[key] : config; } }; })();…  ( 3 min )

    Gradient Descent on Token Input Embeddings: A ModernBERT experiment
    Input Embedding Space Gradients This is the first in a series of posts on the question: "Can we extract meaningful information or interesting behavior from gradients on 'input embedding space'?" I'm defining 'input embedding space' as the token embeddings prior to positional encoding. The basic procedure for obtaining input space gradients is as follows: Transform tokens into input embeddings (but do not apply positional embedding). Run an ordinary forward pass on the input embeddings to obtain a predicted token distribution. Measure cross-entropy of the predicted distribution with a target token distribution. Use autograd to calculate gradients on the input embeddings with respect to cross entropy. The result is a tensor of the same shape as the input embeddings that points in the dire…  ( 7 min )

    Event Sourcing vs. Blockchain: Where Immutability Matters

    Accurate Distance Calculations in Python: Why geopy.geodesic Stands Out
    When working with geographic data in Python, calculating the distance between two points on Earth is a common task. But not all methods are created equal! Here’s a quick guide to the most popular approaches and why geopy.geodesic is often the best choice — especially if you're working on Django, GIS, or logistics platforms. Some libraries (or naive code) use the Pythagorean theorem to compute distance between lat/lng pairs: # ❌ Not recommended for geographic coordinates! from math import sqrt def euclidean_distance(coord1, coord2): return sqrt((coord1[0] - coord2[0])**2 + (coord1[1] - coord2[1])**2) The Earth is not flat.

    The David vs. Goliath Playbook: How Small Teams Can Build Big Tech-Caliber AI Customer Experiences
    For decades, the narrative has been the same, the Big Tech, with its colossal R&D budgets, server farms, and armies of PhDs, sets the standard for customer experience. Their AI-powered recommendation engines, impossibly fast support bots, and hyper-personalized journeys have felt like an unachievable competitive goals. For most startup founders, small business owners, and product leaders, the game seemed rigged honsetly. but guess what That era is over. There are Three fundamental shifts have demolished the old barriers to entry whuich i called the great equalizer The API-fication of Intelligence: Foundation models like OpenAI's GPT-4, Anthropic's Claude, and Google's Gemini are now utilities. You can "rent" a world-class AI brain via a simple API call for pennies. Big Tech did the heavy lifting of training; you get to do the creative work of applying it. The Rise of the No-Code/Low-Code "Nervous System": You don't need a team of machine learning engineers to connect these AI brains to your business processes. Platforms like Zapier, Make.com, and Retool act as a central nervous system, allowing you to build sophisticated workflows that link your CRM, support desk, and marketing tools with powerful AI capabilities—often with zero code. The Agility Advantage: A small team's greatest superpower is its proximity to the customer and its lack of bureaucracy. While a Big Tech company debates a new feature in committee for six months, you can identify a customer pain point on Monday, build a prototype AI solution on Wednesday, and deploy it by Friday. The game has changed. The resources are in your hands, the cost of entry has collapsed, and the agility of a small team has never been more valuable. The question is no longer if you can compete with Big Tech on AI-powered customer experience. The question is, how will you choose to win?  ( 4 min )

    🦀 Understanding Lifetimes, Traits, Enums, and Pattern Matching in Rust
    Rust is known for being safe and fast but to get there, you need to understand some core concepts. Let’s break down lifetimes, traits, enums, and pattern matching with clear examples. Rust makes sure you don’t use data that’s already gone. Lifetimes are how Rust tracks how long references are valid. fn longest(x: &'a str, y: &'a str) -> &'a str { if x.len() > y.len() { x } else { y } } This function returns the longer of two string slices. The tells Rust: "The result reference will live as long as both x and y." ✅ Without this, Rust won’t know how long the returned reference lives and could reject your code to keep things safe. Traits define what methods a type must implement. Think of them like "skills" a type can have. trait Speak { fn speak(&self); } struct Dog; …  ( 4 min )
    Books That Found Me When I Wasn’t Looking
    I didn’t set out to make a reading list. Honestly, most of the books I’ve found useful were ones I stumbled on.

What’s strange is, a lot of them weren’t directly related to work. Not in the obvious way. They weren’t books about “career growth” or “leadership hacks.” But they shifted something in me—how I make sense of chaos, how I ask questions, how I interpret what’s not being said in a room. So no, this isn’t a ranked list. I’m not trying to be helpful or definitive. I’m just trying to trace a line backward—through the ideas, arguments, phrases, and small turning points that stuck.

    Display and Edit DateTime Correctly with Time Zone Awareness in Blazor Server
    Blazor Server makes it easy to build web apps with intuitive syntax, but handling dates and times (DateTime) requires special attention. Can you spot the bug in the following code? @DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss") The answer: This displays the current time on the server, not the user's local time. The time is formatted according to the Blazor host server's time zone, which may not match the user's time zone. This bug occurs when the Blazor host server's time zone ≠ user's time zone. It's a subtle issue that's easy to miss during development. A similar problem arises with date/time input fields.

But a few years ago, I discovered Caddy. The setup was so much simpler. Just a single binary. The config files were actually readable. And the automatic HTTPS just... worked. I haven't deployed Nginx since. These days, I'm building UserJot (a tool that helps teams collect and manage user feedback), and Caddy has been instrumental in keeping our infrastructure simple while we focus on the product. This is a complete, production-ready reverse proxy configuration in Caddy: api.myapp.com { reverse_proxy localhost:3000 } That's it. Three lines. HTTPS included. Certificates auto-generated. HTTP/2 enabled. When I…  ( 6 min )
    VoiceReach [Murf AI Coding Challenge 2]
    VoiceReach is a voice message broadcasting tool that lets users send a single typed message to multiple recipients via automated phone calls. The app uses a Text-to-Speech (TTS) API to convert the message into a realistic voice and then places calls using Twilio to deliver the audio. Designed for quick announcements, invitations, or alerts, VoiceReach eliminates the need for repetitive manual calls, making communication faster and more efficient. Built with Node.js, Express, and a simple HTML/CSS frontend, it's a powerful yet user-friendly solution for voice-based outreach. GitHub repo - https://github.com/madhavdandona123/murf-ai VoiceReach has powerful real-world applications for anyone needing to deliver voice messages to multiple people quickly and reliably. Community leaders, school administrators, event organizers, political campaigners, and small businesses can use it to send announcements, alerts, or invitations without making manual calls. It’s especially useful for reaching people who may not regularly check texts or emails—such as elderly recipients or rural communities. Compared to traditional methods like group calls or bulk SMS, VoiceReach improves efficiency by automating the process with natural-sounding voice and delivering it through a personal phone call, which feels more direct and urgent. It reduces human effort, saves time, and increases the likelihood that important messages are heard.  ( 3 min )
    Build a backend with Cursor and Manifest in just 5 minutes 😲 😵 😱
    TL;DR In this article, I’ll show you how to build a backend in under 5 minutes using Manifest directly from your Cursor IDE. We’ll start from a static real estate listing app and replace static data with a fully functional backend: data, filters, CRUD, and admin panel! If you’re experimenting with AI-powered development, you’ve probably seen two types of tools emerge. First, there are vibe coding tools like Lovable or Bolt. They’re great at turning a short prompt into a polished UI. For quick prototypes, they feel magical. But when it comes to integrating a backend, they hit a wall. You stay stuck with mock data without backend logic. The second are AI code editors like Cursor or Windsurf. These let you code with assistance, directly in your environment. But even then, generating the bac…  ( 8 min )

    Nixopus: Simplifying VPS Management
    This article is my reflection on the journey of how I relied on free tier clouds and platform specific hosting until I discovered VPS. Shipping Code while Sipping Coffee Back then, I was still trying to figure out and understand how all this worked. Starting from which command did what, which service refused to start, and why things that worked on my local; didn’t work when deployed (Thank God for Docker) I still recall one of my earliest deployment. It was github-readme-quotes app on Heroku. A simple git push to deploy felt magical. I didn’t really have to care how it worked. I just knew that if I followed the documentation devoutly, it was assured to work; if not, StackOverflow always had my back. This was the same with Firebase, Render, or Netlify for static stuff.

    Adding Command alias in your Gitbash
    Adding alias in your Gitbash terminal can help you speed up your workflow when using the terminal. ⚡️ In this tutorial, I am going to guide you how you can configure the aliases for your day-to-day commands. 🚀 First of all open the Gitbash and type following command in it. alias And you will see an output something like below image. It will give the list of aliases which are configured. 📋 If you see nothing, then no aliases are set. So don't worry. 😅 To set the alias for any command type following in the terminal. ✨ alias new_command_name='old_command_name' The alias set within the image will create an alias for git commit. Now I can just type gc -m and it will commit my code. 🎯 And that's it, you have configured your first alias. Hurray!!! 🎊 Hold on, it's not over yet. ⚠️ If you just close the terminal and try to re-run that alias again, it will throw error like this. 😱 What?! You will think I just set it and now it's gone. Yup it's gone. 💔 Because aliases set with alias are session based means they are deleted once the terminal is closed off. So how can we make it permanent??? 🤔 Well, there is a way make it permanent. 💡 It's .bash_profile file, it's location differ from OS to OS. For windows it would be OS_Drive/Users/ and for ubuntu it's present in root and you can run ls -la to see it. 📁 Open the .bash_profile file and edit it. ✏️ Congratulations. You have created your first permanent alias, I repeat first permanent alias of your. 🏆 Now you can configure as much as aliases you want, and you just need to add them within .bash_profile file. 🔧✨  ( 4 min )
    A Beginner DBA's Guide to SSRS Reports
    Remember the first time someone asked you to "put that data in a report"? You probably stared at your perfectly good SQL query results and thought, "Isn't this already a report?" Then you realized they wanted something their boss could actually look at without squinting at raw data tables. Here's the thing nobody tells new DBAs: Writing great queries is only half the job. The other half is making that data speak to people who don't think in SELECT statements. That's where SSRS comes in. And no, it's not as scary as it sounds. SSRS (SQL Server Reporting Services) is Microsoft's tool for turning your SQL query results into professional, interactive reports. Think of it as a translator between your database and everyone else. You know that query you wrote to check which products are selling …  ( 5 min )

    The AI Revolution is Here: Are You Ready, or Will You Be Left Behind?
    Hey folks. So what now, fellow developers? Panic, or polish your résumé and lean in? Inside this whirlwind sits both risk and an outsize slice of opportunity that might not show up again in our lifetimes. Let me live-code the explanation for a second. Forget the power-point speak; think of AI as the capability to feed an algorithm mountains of observations and then let it tweak its own playbook as fresh examples roll in. The decision logic emerges from the pattern, not from a human’s final check-mark. Artificial intelligence acquires proficiency in much the same way a specialist absorbs lessons from practice. An influx of fresh information typically translates into perceptible improvement. Professors and practitioners usually separate three principal disciplines within the field. Machin…  ( 6 min )

    From Rejection to Redemption: How I Landed My SRE Role

    This Is How I Mastered TypeScript Like I'm 5 (And How You Can, Too!)
    Today! We’re going to learn TypeScript like you’re a smart 5-year-old who loves to build things and asks “why?” (which is the best thing ever). & yes “why?” is my way of learning. I've divided this into 20 Chapters. and will go one by one and each will be of 2 - 3 min. of read. This is Chapter ⓵ TS Mastering 🤔 Imagine this: You’re building a toy robot (Yes, we are learning it like 5) . In JavaScript, you just glue parts together however you like even if you accidentally attach a banana instead of a motor… the robot won’t complain until it breaks later! 🍌🤖💥 But with TypeScript, it’s like having a smart helper who says: “Hey! That’s not a motor... that’s a banana. Are you sure you want to do that?” That helper saves you from mistakes before you even turn on the robot. Cool, right? TypeScript = JavaScript + Superpowers (called Types) write safer, smarter code. TypeScript helps you catch errors early It makes your code easier to understand It works great with modern tools and editors 💬 Let’s look at a simple example: // JavaScript function add(x, y) { return x + y; } add(5, "10"); // 🙃 oops! This gives "510" instead of 15! Now in TypeScript: function add(x: number, y: number): number { return x + y; } add(5, "10"); // ❌ ERROR! You gave me a string, I wanted a number! TypeScript tells you before you even run it that something’s wrong. Yes‼️ TypeScript is just JavaScript with extra safety. type annotations. 🐞 Catch bugs before they happen 👯‍♂️ Work better in teams 💻 Get amazing auto-suggestions in your code editor If you enjoyed this and want to master TypeScript and other technologies, follow the series and drop a like!🤝 I’m a passionate software developer sharing the cool things I discover, hoping they help you level up on your coding journey.

    Getting Better with Figma: Day 1
    Day One was me reacquainting myself with Figma. I started by reviewing the basics of the interface and exploring the various tools and features available. I also took some time to familiarize myself with the keyboard shortcuts and the different ways to navigate the canvas. Juxtopposed video on this was super helpful and is what kicked off this idea! Who doesn't like cards on websites. They come in all sorts of... well not shapes but sizes and designs. I've seen truly beautiful ones and wanted to get better with playing with multiple layers. I knew I wanted a simple card consisting of a header, small paragraph, an icon, and a gradient. I often see cards come in threes and when I'm playing with colors in counts of three it's very difficult for me to not think of Pokémon, so I just went with it! There are actually several layers to each card: A circle with it's midpoint roughly anchored to the card's bottom right corner. A rectangle above it acting as a mask for the circle and bringing in the darker emerald/blue/rose colors. A rectangle of the same size above that with a semi-opaque and lighter emerald/blue/rose color with an inner-shadow of the darker color. The text and icon are the final layers. Even the button has a semi-transparent background which allows the main color to bleed through, as well as a semi-transparent border. These are simple but I like them! There is no goal to do one per day, but I’d like to do at least four three week so I can see progress. I also plan to write a short blog (or micro-blog, if you will) about each design I create or copy. If you’re in a similar boat, I encourage you to jump on board and do the same! I’ll be sharing my progress on X/Twitter and LinkedIn. If you’re interested in following along, feel free to follow me on those platforms!  ( 3 min )

You point at things, gesture wildly, maybe even draw pictures — anything to communicate what you want. But if you and the server spoke a common language like English or Spanish, things would go a lot smoother. That’s exactly what APIs do for software systems. They are shared languages that define how software components talk to each other. Without a shared API, systems can't collaborate…  ( 8 min )

    The Role of AI and Compliance in Modern Risk Management: ShowMeCon 2025
    When people think of St. Louis, it's often the Gateway Arch or the Cardinals that come to mind. Just across the Missouri River is one of the "Show Me" state's oldest European settlements, dating back to 1769, St. Charles. Front just a stone's throw from where Lewis and Clark set off on their famous expedition, something more than baseball statistics, historical trivia, or architectural wonders was being discussed in early June: security, compliance, and risk, at ShowMeCon 2025.  Around 400 practitioners gathered for two full days of sessions, villages, and a CTF run by MetaCTF. There was much discussion of the industry's distinction between controls, policies, and security. A general theme emerged that real security demands context, rigor, and adaptive posture, not just checking the box.He…  ( 7 min )

    Docker containers vs. Virtual machines: What's the difference?
    If you are a developer or a system administrator, you might have heard of Docker and Virtual machines. Both are technologies that allow you to run applications in isolated environments, but they have different advantages and disadvantages. In this article post, I will compare Docker containers and virtual machines, explain their use cases and examples, and help you decide which one is better for your needs. A virtual machine (VM) is like a mini-computer that runs inside your main computer. It has its own operating system, memory, disk space, CPU, network interface, etc. You can run any application on a VM as if it was running on a real computer. For example, you can run Windows on a VM inside your Linux computer, or vice versa. Some of the benefits of using VMs are: They provide full isola…  ( 5 min )

    What stability looks like in DeFi: a data-driven look at WBT's behavior in 2025
    DeFi isn’t exactly known for stability. Between hype cycles, market-wide volatility and social-media-triggered moves, most tokens tend to mirror the chaos around them. But every now and then, a token breaks that pattern. In 2025, $WBT coin has shown a different trajectory - not only resisting downturns, but reaching five new all-time highs in less than six months! While most centralised exchange tokens ($BNB, $OKB, $KCS, $GT) have stayed flat or fallen below their historical highs, $WBT has continued climbing. For reference: $BNB hit its ATH of $788.84 in Dec 2023 and hasn't surpassed it since $OKB last peaked in Mar 2024 $KCS hasn’t seen a new ATH since 2021 $GT joined WBT in reaching a new ATH in 2025 🧨 There are several macro signals that align with WBT's recent rise, and prove its growth as infrastructure-backed: trading volume surged alongside each ATH; liquidity pools deepened, especially post-margin launch; holder count steadily increased (on-chain data shows consistent wallet growth). WBT's case challenges a common assumption in crypto: that price action must come from hype & artificial pump. In contrast, it shows that consistent development, deep integration and clear tokenomics can still drive growth - even in noisy market conditions. For a deeper dive into WBT's recent performance, check the full article from CoinMarketCap. If you're building in 2025, WBT is a reminder that steady growth still comes from solving real problems, not just riding trends.  ( 3 min )

    UI/UX - CSS でスタイル定義
    CSS とは Web ページの見た目を装飾するのが CSS (Cascading Style Sheets) です。HTML でページの骨格を作り、それに対して CSS で色、フォント、レイアウトなどを指定します。 CSS では、HTML 要素にスタイルを適用するためのルールを記述します。 セレクタ { プロパティ: 値; プロパティ: 値; } 用語 説明 例 セレクタ どの HTML 要素にスタイルを適用するかを指定します。 (下記「セレクタの種類」参照) プロパティ 変更したいスタイルの種類 color, font-size, margin 値 プロパティに設定する具体的な値 blue, 16px, 10px 20px セレクタは以下の 3 種類に大別されます。(疑似要素を含めるともう少し増えます。) これらを使い分けることで、スタイル適用範囲に幅と柔軟性を持たせることができます。 種類 例 要素セレクタ p { color: blue; } (すべての 要素) class セレクタ .my-button { background-color: green; } (タグに class="my-button" 属性を持つ要素) ID セレクタ #header { font-size: 24px; } (タグに id="header" 属性を持つ要素) h1 { /* 文字色を濃いグレーに */ color: #333; /* フォントサイズを 32 ピクセルに */ font-size: 32px; /* テキストを中央揃えに */ text-align: center; } .button { /* 背景色を青に */ background-color: #007bff; /* 文字色を白に */ color: white; /* 内側の余白 */ padding: 0.2em 0.4em; /* 枠線をなくす */ border: none; /* 角を丸くする */ border-radius: 0.2rem; /* マウスカーソルをポインターに */ cursor: pointer; } .container { /* この要素を Flexbox コンテナにする */ display: flex; /* 子要素の水平方向: 両端に配置 */ justify-content: space-between; /* 子要素の垂直方向: 中央に配置 */ align-items: center; } Vue ではスタイルをどこに書くのでしょうか。 一つの方法は、すでに見た単一ファイルコンポーネント (SFC) すなわち .vue ファイルの中で タグに記述する方法です。そのコンポーネントに特化した CSS を記述できます。 共通のスタイルやユーティリティ class 定義を外部ファイル (.css) に記述することも可能です。希望の場所で読み込んで使用します。  ( 3 min )
    A Classic Reborn: How I Remastered 40 Puzzle Games with AI
    I've been a longtime fan of a puzzle website with 40 incredibly well-made intellectual games. Recently, I decided to give it a modern overhaul. I don't have much front-end development experience, so I used Cursor and Claude to assist me throughout the process. I want to share why I decided to refactor this classic collection and how I efficiently accomplished this task with the help of AI, especially tools like Claude. Many years ago, I first encountered Simon Tatham's Portable Puzzle Collection. It's a set of brilliantly conceived and logically rigorous games, all written in C, capable of running on various old devices. I was hooked, completely captivated by their clever design. I even took a look at his C source code, and it's beautifully written. The author also developed PuTTY, which i…  ( 6 min )

    Relax About Your DORA Metrics
    Our jobs require a certain level of precision, so it’s natural that we’ll want to take an exact approach to our software delivery metrics. Some folks might even like a detailed standard to pin their measurement to so they can be sure it’s exactly right. Investing too much in precision is wasteful and takes time away from something far more important: doing something in response to the data. The DORA metrics are the most popular DevOps metrics. The precision needed for DORA metrics is low, and gets even lower the higher you perform. In general, you want to get a temperature check for the kind of performance you have. For the throughput metrics, the unit of measurement is more informative than the number. It’s more interesting whether you measure throughput in months, weeks, days or hours th…  ( 6 min )

    Improving Next.js Performance: SSR to SSG + ISR for Faster Load Times
    Page speed matters more than ever. Google’s Core Web Vitals framework has made TTFB and FCP crucial for ranking well. After hitting limitations with SSR, we decided to move to SSG + ISR on two of our most active content sites: nolcardbalanceae.com — public transport and NOL card balance check guides wgustudentsportal.com — student tools and academic resources Both platforms initially used getServerSideProps, but with traffic rising and SEO slipping, performance audits with PageSpeed Insights and Lighthouse confirmed what we feared: server response time was hurting the experience. We migrated to getStaticProps with Incremental Static Regeneration (ISR), letting us statically generate thousands of guides and tools for both nolcardbalanceae.com and wgustudentsportal.com. return { The result? Pages served instantly, with fresh data reloading in the background. Vercel’s 45-minute build limit created a blocker during deployment. With so many static pages, we exceeded the threshold regularly. To fix it: We batched content at build time Stored it as local JSON Called that in getStaticProps() This brought total build time below 30 minutes and gave us predictable, fast deployments. After implementation: nolcardbalanceae.com saw bounce rate drop by 20% wgustudentsportal.com pages loaded under 1 second Lighthouse scores consistently hit 95+ Googlebot crawled 3× more URLs per day We followed Next.js best practices and Google’s performance guidelines to the letter — and it paid off.  ( 3 min )

That’s why I built @ts-migrating, a plugin and CLI tool that helps you progressively upgrade your tsconfig.json without breaking your codebase or your team's velocity. tsconfig When you switch on a stricter compiler option, you immediately see a flood of new type errors. It is overwhelming. Realistically, your team does not have the time to fix everything in one go, and trying to do so is a recipe for burnout and regressions.

    Your Code Is a Houseplant: Why Most Projects Would Die Without Code Reviews
    Let’s get something straight: your code is not a majestic redwood. It’s a houseplant. A needy, fickle little thing that demands regular sunlight, occasional pruning, and a watchful eye—lest it curl up, die, and stink up the whole damn repo. And like any fragile flora, it’s going to wilt if you abandon it. Enter code reviews: the unsung gardeners of your software jungle. Here’s the truth no one wants to say out loud: Most code isn’t great the first time. Or the second. Or the third. It’s a miracle anything even compiles. Left alone, developers will create beautiful chaos—clever hacks, unchecked tech debt, and naming conventions that double as inside jokes. Without code reviews, a codebase becomes that weird succulent your coworker left behind: slowly dying, too awkward to throw away. Code r…  ( 4 min )

    🚀 Unlocking the Power of Generative AI with LangChain: A Practical Look at LLMs in Action
    Generative AI has exploded into the mainstream, with Large Language Models (LLMs) like GPT-4 leading the charge. But as impressive as these models are, integrating them into real-world applications requires more than just an API call. That’s where LangChain comes in. In this post, I’ll walk you through how LLMs and Generative AI work together — and why LangChain is becoming the go-to framework for building intelligent, context-aware AI applications. At its core, an LLM is a machine learning model trained on vast amounts of text to understand and generate human-like language. When we talk about Generative AI, we refer to systems that can create — be it text, images, music, or code. LLMs are a major driver of this new creative paradigm. LLMs are great at: . Answering complex questions But th…  ( 4 min )
    The Algorithmic Classroom
    For centuries, the image of education has remained stubbornly consistent: a teacher imparting knowledge to a room of students. But beneath the surface, a quiet revolution is underway. Artificial intelligence is no longer a futuristic fantasy; it’s actively reshaping how we learn, how we teach, and even what we learn. This isn't simply about digitizing textbooks or automating grading—it’s a fundamental shift in the architecture of education, a move toward systems that adapt, personalize, and anticipate the needs of every student. But the promise of AI in education isn’t without peril. As algorithms permeate the classroom, critical questions around equity, privacy, and the very nature of human learning demand urgent attention. The limitations of a one-size-fits-all curriculum are well docume…  ( 7 min )
    Implementing a Simple Static File Server in a Lightweight Python Web Framework
    Serving static files—like CSS, JavaScript, images, or fonts—is a basic requirement for any web application. Even in a minimal Python framework, you can add support for static file delivery with only a few lines of code. Static assets are essential for rendering pages and enhancing UX. Without them, even the most functional web app will look and feel incomplete. You may use a reverse proxy (like Nginx) in production, but during development or for embedded apps, your framework should handle static file serving directly. To serve static files: Match requests with a /static/ prefix Map the request path to a file in a designated directory Read the file’s contents Return the appropriate content type in the response A simple folder layout: myapp/ static/ style.css logo.png app.py …  ( 4 min )
    Building Middleware Support in a Lightweight Python Web Framework
    Middleware allows you to process requests and responses as they pass through your framework. It’s a powerful way to add features like logging, authentication, CORS, or response headers without modifying core logic or handlers directly. Middleware is a function that wraps around the request/response cycle. It can modify the request before it reaches the handler or alter the response afterward. In a lightweight framework, middleware should be simple, composable, and optional. At its core, middleware can be a callable that takes two arguments: The request object A next_handler function it can call to continue processing Here’s a minimal middleware structure: def middleware(request, next_handler): # do something before response = next_handler(request) # do something after retu…  ( 4 min )

    From RAG to Multi-Agent AI for Job Matching
    A while back, I wrote a blog post about building an AI resume matcher using a RAG approach with Java and Google Vertex AI. I originally built a RAG-based AI to match resumes against job postings using a vector store. It was a fantastic project, but it got me thinking: how could this be even more intelligent and nuanced? That question led me straight to the Google ADK Hackathon. The challenge was to build autonomous multi-agent systems, which felt like the perfect evolution of my previous project. So, I decided to tackle the same problem job matching, but with a completely new architecture. In this post, I'll walk you through my journey building JobMatch AI and explore why a multi-agent system was a game-changer. 🚀 Let's get started! The core problem remains the same: finding the right job…  ( 7 min )

    🚀 A Smarter WordPress Launch Strategy for 2025 (Checklist Included)
    Launching a WordPress site in 2025 isn’t just about spinning up a theme and hitting “publish.” With users expecting faster performance, mobile responsiveness, and secure UX out of the gate — your launch process has to be strategic. I’ve launched sites for clients and personal projects, and I noticed a recurring pattern: the same pre-launch mistakes cause headaches later. So I started using a structured checklist — and it’s made all the difference. Here’s a breakdown of what I now do before going live with any WordPress site. Choose a reliable host (SSL, backups, fast support) Register a clean, brandable domain Ensure server location suits your target audience (e.g., US-based server for US traffic) Yoast SEO or Rank Math (SEO) UpdraftPlus (backups) Wordfence or Sucuri (security) Elementor or block-based editor for layout Use a responsive, lightweight theme Customize branding elements (colors, fonts, CTAs) Test across breakpoints (mobile/tablet/desktop) Enforce strong passwords & 2FA for admin users Update all plugins/themes before launch Install firewall + login protection plugin Meta titles + descriptions XML sitemap submission Keyword-optimized content + internal linking Compressed images + alt tags Google’s Mobile-Friendly Test ✅ Optimize for Core Web Vitals (LCP, FID, CLS) Check tap targets, menu responsiveness No broken links or 404s Contact forms working Speed test (PageSpeed, GTmetrix) Full backup before going live I’ve put together a detailed checklist that includes exact tools, plugins, and tips I use with clients.

    Decorators in Python: What you need to know
    I remember the first time I struggled to add the same extra behavior to many functions. I had a logging requirement on every class method, so I tried subclassing or adding if checks everywhere. My code became a tangled web of inheritance and flags. Then a colleague showed me decorators – and my mind was blown. A decorator is like giving your function a special coat: you wrap extra behavior around it without changing its core logic. As one tutorial puts it, decorators “allow you to wrap another function—to add or modify its behavior—without changing the original function’s code”. It felt as elegant as putting a gift in a beautifully decorated box. enhances it. In the same way, a decorator takes your function and adds “frosting” – extra logging, timing, authorization checks, etc. You still …  ( 8 min )
    You Might Not Need useEffect Anymore in React
    _useEffect_ became the most frequently used and, at the same time, the most frequently misused hook in React since its release. It was used to do everything: data retrieval, state synchronization, event listening, and even lifecycle. However, with the development of React, its best practices change. The introduction of React 19, Server Components, Server Actions, and other developments such as the React Compiler (Forget) are leading the ecosystem towards a more declarative, reactive and server-focused paradigm.

Brute Force Idea: Check every number starting from 1, See if it's a palindrome in both base 10 and base k. Keep going until I find n such numbers. This idea is simple, but extremely slow and will TLE for large n. What I Figured Out: I realized that we should generate palindromes only in base 10 and check if they’re also palindromes in base k. This eliminates checking non-palindromic candidates, which saves a lot of time. I also figured that we can build palindr…  ( 4 min )

    I Built a Chrome Extension to Save ChatGPT Chats — Here’s How and Why
    👋 Introduction: Ever lost an important ChatGPT conversation due to a refresh or message limit? I did — way too many times. That’s why I built ChatBridge, a lightweight Chrome extension that lets you save and resume your ChatGPT chats any time. No servers. No logins. Just simple, offline chat memory. 💡 The Problem: ChatGPT is powerful, but one frustrating limitation is the lack of persistent memory in the free version. Once you refresh the page or hit your message limit — poof 💨, your chat is gone. If you’re using it for research, writing, or learning, it’s a huge productivity loss. 🛠️ The Solution — ChatBridge ChatBridge gives users the ability to: Paste a chat into the popup Title it for easy recall Save it to local storage Reopen anytime — even offline It’s a simple way to give ChatGPT a “manual memory.” ⚙️ How I Built It: Stack: HTML5 / CSS3 JavaScript (ES6+) Chrome Extension APIs localStorage for persistence The extension runs entirely in your browser. Nothing leaves your device. I used manifest v3 and added a user-friendly popup UI with auto-updated saved chat history. Handling edge cases like refreshes and repeated saves Designing a minimal yet functional UI 📦 Try It Out: 👉 GitHub Repository - https://github.com/pratibha131/chatbridge-extension It’s open-source and easy to install via chrome://extensions → "Load Unpacked". 🙌 What’s Next?

    How CPU Interacts with GPU 🕹
    The CPU interacts with the GPU through the system's bus (usually PCIe) and driver-level APIs. Here's a breakdown of the process: CPU Prepares Work Runs the main game or application logic. Determines what needs to be rendered (e.g., scene, camera angle, models). Sends Commands to GPU Uses graphics APIs like: DirectX (Windows) OpenGL / Vulkan Metal (macOS) These APIs translate CPU intentions into GPU-friendly instructions. Data Transfer via PCIe CPU sends: Textures Geometry (models, vertices) Shaders Instructions All transferred over the PCIe bus into the GPU's VRAM. GPU Executes Tasks GPU receives and processes rendering tasks in parallel. Uses thousands of cores to efficiently compute visuals. Result Output to Display GPU sends the final rendered frame to the display via HDMI or DisplayPort. CPU = Director: Plans and instructs. GPU = Worker: Executes rendering and parallel computations. Communication relies on PCIe bus and graphics APIs.  ( 3 min )

    Run MCP Servers In Seconds With Docker
    Model Context Protocol (MCP) has taken the AI world by storm. It has become the de facto standard for how an AI Agent connect with tools, services, and data. As this is shaping up rapidly, working with different MCP servers, setting them up is still not an easy task, and it requires a learning curve. Docker has a track record of making developers’ lives easier to make, build and ship things faster and again it chimes in to the MCP space, bringing that same clarity, trust, and scalability.

    How to Set Up Config Auto Sync in SafeLine
    SafeLine version 7.x introduces a config auto sync feature, allowing you to set up master and slave nodes. This feature automatically synchronizes the master node's configuration to slave nodes every minute. In case the master node fails, users can manually switch traffic, enabling slave nodes to immediately handle business traffic. Verify that the SafeLine versions on both master and slave nodes are identical (including minor version numbers) Ensure that the SafeLine licenses on both master and slave nodes are consistent (both professional version) Verify network communication between master and slave nodes is operational Setting Up the Master Node Designate one device as the master node View the commands that need to be executed on the slave node. Save these commands as you will need to execute them on the slave node machine Setting Up the Slave Node Designate a device as the slave node Execute the binding command obtained from the master node on the slave node—you must get this command from the master node console as described above Check the result after execution. The image below shows successful execution View the master node display View the slave node display. Note that the slave node cannot modify configurations (operations are disabled by default) Test configuration synchronization by making changes on the master node and checking whether they are successfully synchronized to the slave node Configuration synchronization does not include logs and statistical information Click the unbind button on the right to disconnect configuration synchronization How many slave devices can a master device have?

    Pushing Billion-Scale Vector Search Beyond RAM Limits with DiskANN
    The Memory Wall Problem Most vector indexes prioritize RAM for low latency. HNSW, for example, achieves 95% recall at <5ms for 100M vectors but requires ~500GB RAM. At 1B vectors, RAM costs exceed $10k/month on cloud instances—prohibitively expensive for many teams. DiskANN flips this model: Core Innovation: Stores graph structure and full vectors on SSDs Memory Footprint: Requires 15–50× less RAM than HNSW Tradeoff: Accepts ~10–20ms latency (NVMe SSDs) for billion-scale searches In my 1B vector test (768-dim), DiskANN used 32GB RAM versus HNSW’s 512GB while maintaining 95%+ recall. How DiskANN Breaks the Tradeoff DiskANN’s performance stems from two key innovations: 1.

    Structured Text computing: SPL Practice
    Structured Text Computing Requirements Structured text files are a common data storage method, such as this score.txt file, which records the scores of students in all classes. The first row is the column name, and each subsequent row is the data of a student, separated by tab within each row. Importing into a database and using SQL to calculate is certainly not a problem, but the process is complicated and there may not always be a database available. Writing Java code is also very tedious, but using SPL is very simple. First, let's see how to load the file. The import() function of A1 can directly read the structured text file into an in-memory data table. The @t option represents the first row is field name. For comma separated CSV files, the option @c can be used to read in, and @tc…  ( 15 min )

    Efficient Routing Techniques in a Lightweight Python Web Framework
    Routing is the core mechanism that connects HTTP requests to the appropriate code handlers. In a lightweight Python web framework, implementing efficient and flexible routing allows you to build clean URLs, handle dynamic parameters, and organize your app logically. When a client sends a request, the framework must decide which function or method will process it. Routing takes the request path and HTTP method, then matches it against predefined patterns to find the correct handler. The simplest routing matches fixed paths: /home → serves home page /about → serves about page You can store routes in a dictionary keyed by path: routes = { "/": home_handler, "/about": about_handler, } Lookup is then a quick dictionary access. Real apps need dynamic routes like /users/42 where 42 is …  ( 4 min )
    Understanding Docker: part 49 – Docker Compose (2025)
    Understanding Docker can be difficult or time-consuming. In order to spread knowledge about Cloud technologies I started to create sketchnotes about Docker. I think it could be a good way, more visual, to explain Docker (and other technologies like Kubernetes and Istio). We continue the series of Docker sketchnotes with a focus on Docker compose included all the latest features: publish compose file as an OCI artifact and use it, transform compose files to Kubernetes manifests, providers usage like from Docker Model Runner... As usual, if you like theses sketchnotes, you can follow me, and tell me what do you think. I will publish others sketchs shortly :-). If you are interested, I published the book in a paperbook version on Amazon: Understanding Docker in a visual way and also in a PDF/ebook version on GumRoad. If you are also interested in Kubernetes, the book Understanding Kubernetes in a visual way is available also.  ( 6 min )

    CQRS Pattern in Nest.js
    As your applications grow in complexity, so does the challenge of organizing business logic in a maintainable and scalable way. One pattern that addresses this challenge is CQRS — Command Query Responsibility Segregation. In this article, you'll learn what CQRS is and how it works, when to use (and avoid) CQRS, and how to implement CQRS in a real-world NestJS application using the @nestjs/cqrs module Enjoy CQRS stands for Command Query Responsibility Segregation. It’s an architectural pattern that separates the responsibilities of: Commands: actions that change state (e.g., create, update, delete) Queries: actions that read data (e.g., get list of tasks, fetch user info) This separation contrasts with traditional CRUD, where reads and writes are typically handled by the same service or con…  ( 4 min )
    How to Increase or Decrease Laravel Session Lifetime
    This guide will walk you through adjusting the session timeout duration in your Laravel application. You’ll explore two straightforward techniques: Editing the .env file Editing the config/session.php configuration file Both approaches are compatible with all major Laravel versions — from Laravel 5 up to Laravel 12. A Laravel session is a way for your web application to remember information about a user across multiple page visits. Think of it like this: When someone visits your website and logs in, the session acts like a temporary memory that stores key details — like their user ID or login status — so they don’t have to log in again every time they visit a new page. Laravel handles this automatically behind the scenes. It gives each visitor a ** unique session** ID (usually stored in a browser cookie), and stores the data either in files, a database, or another storage system — depending on how your app is set up. Open your .env file , by default SESSION_LIFETIME *is **120 minutes *, which means user sessions will expire after **2 hours of inactivity. Modify the SESSION_LIFETIME value in your .env file: SESSION_LIFETIME=525600 # 1 year (60 minutes × 24 hours × 365 days) For a shorter session, like 30 minutes: SESSION_LIFETIME=30 Laravel will automatically use this value to control how long a session remains active. open, the session.php ,Alternatively, you can define the session lifetime directly in the config/session.php file: 525600 , # 1 * 60 * 24 * 365 ..................................................... ]; If you've updated the session lifetime in config/session.php but it's not reflecting in your application, make sure to: 👉 Want the full code and detailed explanation?

    CapacitorJS: One code base  -  many platforms
    What is CapacitorJS? CapacitorJS is an open-source runtime developed by the Ionic team. It wraps your web application in native containers, giving it access to native APIs - effectively turning your web app into a mobile app for Android and iOS, without abandoning the comfort of modern frontend tooling. The learning curve is fairly approachable, especially if you already have experience with frontend frameworks like React, Vue, or Angular. But don't be fooled by its simplicity - Capacitor has a lot going on under the hood. I'm not suggesting you should ditch native development entirely. Capacitor isn't a silver bullet, and for complex applications requiring intensive native features, traditional Android/iOS development still reigns supreme. That said, if you're working on a startup produ…  ( 4 min )
    How to prioritize test cases for automation in a fintech environment
    What’s the cost of a single bug slipping into your FinTech app’s production environment? For some teams, it’s a minor support ticket. For others, it’s an emergency rollback, an audit failure, or worse – a social media storm followed by thousands of users deleting the app. Now multiply that risk by the velocity of your releases. The average FinTech platform deploys multiple times per week. Each release introduces new features, touches old logic, and reawakens forgotten bugs. Every push is a potential trigger. The numbers aren’t comforting. According to Statista, 6 out of 10 users will abandon a banking app due to performance issues. Not poor UX. Not pricing. Performance. Almost two in three people who begin a digital application do not complete it - a 23% increase in abandonment rates since…  ( 8 min )

    You Don’t Need More Features—You Need Better Onboarding
    Ever launched a product and thought: "If I just add one more killer feature, users will finally get it." But they don’t. They bounce. They churn.

    The Dark Art of Safe Rebasing: Mastering "Onto" in IDEs and CLI
    Git rebasing can sometimes feel like deciphering a cryptic incantation—especially when your IDE throws around the term “onto” without clear context. Whether you’re working with the intuitive interface of IntelliJ or the plain commands on the terminal, understanding what “onto” means is essential. At its core, the rule is simple: The branch on the left-hand side (LHS) is the one that gets rewritten, while the branch on the right-hand side (RHS) remains safe. In practice: Always have your stable branch (usually main) on the RHS. In this post, we’ll first break down how IntelliJ presents this concept and then show that the same logic applies on the Git CLI. When working with IntelliJ, you’ll often see rebase options that explicitly mention both branches. Typical examples are: Rebase feature…  ( 4 min )

    AES and Symmetric Key Encryption: The Key to Reliable Data Security
    In modern society, various forms of data, such as personal information, financial records, and corporate secrets, are stored and transmitted digitally. Such data is vulnerable to theft or alteration by malicious attackers. Therefore, robust security measures are essential. Data protection helps preserve the confidentiality and integrity of information while maintaining the trust of users and organizations. Symmetric key encryption is a method that uses the same key for both encryption and decryption. This approach is widely used due to its high processing speed and relatively simple implementation. However, if the key is exposed, security can be compromised, so proper key management is crucial. Symmetric key encryption forms the foundation for secure communication and data storage.

It allows efficient querying based on the relationships between these separate tables. Relational databases store and manage data in multiple normalized tables. JOIN serves as a key tool that combines data from these tables based on their relationships. By using JOIN, it is possible to reduce duplication and maintain data integrity while easily integrating and retrieving data according to various conditions. This makes JOIN indispensable for data analysis and report generation. JOIN connects…  ( 6 min )
    🏛️ Stop Writing Brittle Tests: Your Blueprint for a Scalable TypeScript POM
    🤖 In our last article, we mastered Custom Types, creating a safety net for our test data. We learned how to define the exact shape of our data payloads and API responses. Now, it's time to build the structure that will house our test logic: the Page Object Model (POM). Think of it like this: so far, you've been building with scattered piles of wood and nails. Your tests might work, but they're messy, hard to read, and break easily when the UI changes. This article gives you the architectural blueprint—the Class—to build a sturdy, scalable, and maintainable test automation framework. We will use TypeScript's most powerful features to build a POM that is not just effective, but a joy to work with. This guide assumes you are comfortable with the concepts from our previous article and have a …  ( 9 min )
    What do you think of this?
    Hey guys, I wanted to share an open-source chat app that we built last week as part of the T3 Clone Competition. It’s a minimal AI chat app inspired by t3.chat, with most of the core features replicated: Google + Anonymous auth with chat linking Multi-model support (OpenAI, OpenRouter) Real-time updates with Convex File uploads (PDF, image, text) Chat branching and shareable threads Syntax highlighting, markdown support Bring-your-own-key support (keys never touch the server) The branching + share feature was the trickiest—it required snapshotting and spinning up isolated threads when someone replied to a shared chat. You can try it live at 👉 https://ch4t.codse.com source code is open at 👉 https://github.com/codse/chat Not perfect (still missing image generation and smoother streaming), but it was a fun deep dive into real-time UX.

    From Gantt Charts to Agile Sprints: Adapting Maritime Project Rigor to Software Delivery
    What marine dry-docking taught me about Agile delivery in software—and how to lead both without sinking the ship. Originally published on Medium There’s a reason ships don’t run late: the plan must hold. But in software, the winds change faster. I’ve learned to sail both seas. I didn’t start in tech. I started in the engine room — where the schedules are tight, the budgets tighter, and failure is not just expensive, but dangerous. As a marine project manager, I lived and breathed Gantt charts, SMS audits, and budget-driven milestones. Timelines were sacred. Stakeholders included flag states and classification societies. Your ability to predict and manage risk was your credibility. Then I transitioned into software delivery — building life-critical safety platforms. What surprised me most w…  ( 5 min )

    I rolled my own auth
    So against popular advice, I rolled my own auth and wanted to share. It still has a long way to go, and I absolutely do not want to compete with the SaaS providers, nor do I want to compete with big, professional packages like KeyCloak and Authentik. I just wanted to write something that was easy to use and covered most small use cases. I put together a blog post detailing the journey that led me to do something so foolish, and I hope people can relate. Github repo for microauthd. Right now, it sports a dual-server, dual-key architecture, has web, cli & JSON/HTTP (faux REST) configuration/admin interfaces, and is written in C# (.NET 8) to allow for ahead-of-time compilation (AOT). The binary sits at 26MB, the memory commit @ rest is 57MB, and startup time is sub-50ms on Windows. Linux builds are similar, if not a bit snappier. I have not yet tested on MacOS, but expect it to run fine there too. I have basic libraries for Python & Go (very basic), and testing is done via Python harness. Remember, my goal isn't to compete with the big boys; I just wanted build something solid for my use cases. That went well, so I beefed it up a bit for more general usage. I just want to put something solid out there and iterate on it until it's ready for more general use.  ( 3 min )

    2081. Sum of k-Mirror Numbers
    2081. Sum of k-Mirror Numbers Difficulty: Hard Topics: Math, Enumeration A k-mirror number is a positive integer without leading zeros that reads the same both forward and backward in base-10 as well as in base-k. For example, 9 is a 2-mirror number. The representation of 9 in base-10 and base-2 are 9 and 1001 respectively, which read the same both forward and backward. On the contrary, 4 is not a 2-mirror number. The representation of 4 in base-2 is 100, which does not read the same both forward and backward. Given the base k and the number n, return the sum of the n smallest k-mirror numbers. Example 1: Input: k = 2, n = 5 Output: 25 Explanation: The 5 smallest 2-mirror numbers and their representations in base-2 are listed as follows: base-10 base-2 1 1 3 11 5 101 7 111 9…  ( 28 min )

    Cross-Language Model Inference Without Python: An Engineering Perspective
    When deploying AI models in enterprise environments, I’ve encountered a recurring constraint: production systems often prohibit Python runtime dependencies. While working on a compliance-sensitive project requiring local text embedding for a 10M-vector dataset, I needed a solution that could integrate directly with Java-based infrastructure. Here’s what I learned about bridging this gap using ONNX and alternative toolchains. Most open-source AI models (e.g., Hugging Face’s sentence-transformers) assume Python availability for: Tokenization (splitting text into model-digestible units) Inference (transforming tokens into embeddings/predictions) Post-processing (normalizing outputs) In my case, compliance requirements eliminated cloud API options.

    Destructuring Arrays
    The Core Idea Destructuring is a special syntax that allows you to "unpack" values from arrays or properties from objects into distinct variables. Think of it like this: You have a box (the array) with several items inside. Instead of carrying the whole box around just to get one item, destructuring lets you reach in and pull out the specific items you want, giving each one a name. Before destructuring, if you wanted to get the first and second elements of an array and assign them to variables, you would do this: const userProfile = ['John', 'Doe', 30, 'Developer']; // Accessing elements by their index number const firstName = userProfile[0]; // 'John' const lastName = userProfile[1]; // 'Doe' const age = userProfile[2]; // 30 console.log(firstName); // Output: John console.log(…  ( 5 min )

    Technical Frontend Deep Dives for Web3 Developers
    If you’re like me—a frontend dev who cut their teeth on design and found their freedom in crypto—then you know that building for Web3 is a constant tug-of-war between complexity and elegance. In this post, I’m diving into three of the most important frontend techniques that have helped me scale real-world dApps without losing sleep (or my users). Global state in Web3 isn’t just UI fluff—it can represent real token balances, on-chain auth, wallet connections, and smart contract interactions. Redux is a beast. It’s overkill for the lean, reactive needs of most Web3 dApps. Zustand and Jotai, on the other hand, give you atomic state management with way less boilerplate. import { create } from 'zustand'; const useWalletStore = create((set) => ({ address: null, setAddress: (addr) => set({ ad…  ( 4 min )

    Turn Any Topic into Viral AI Videos Using Google’s VEO3 model
    I've been hearing a lot about these new AI video models that look incredibly realistic lately. People are actually creating entire TikTok channels based on them, and they look surprisingly good! I never really tried them myself, so I wanted to check them out. I decided to start with Google's VEO3 model that everyone seems to be talking about. Instead of manually creating prompts and videos one by one, I developed an AI automation that will take any topic you have and turn it into banger videos. This way, I could quickly test the model's capabilities and see if it lives up to the hype. So in this tutorial, I'll walk you through how I built this automation to: Generate creative video ideas from a simple topic input Craft optimized prompts for Google VEO3 Produce high-quality AI videos wi…  ( 9 min )

    Angular 20 : Giving the correct prompt’s for LLMs
    TypeScript Best Practices TypeScript is the foundation of Angular applications. Clean, type-safe code reduces bugs and enhances maintainability. Enable strict mode in your tsconfig.json to catch potential issues at compile time. { "compilerOptions": { "strict": true } } Let TypeScript infer types when the type is obvious, to reduce verbosity: const name = 'Angular'; // inferred as string any; Use unknown Instead Using any disables type checking. If you must accept uncertain data, prefer unknown and refine it safely: function process(data: unknown) { if (typeof data === 'string') { console.log(data.toUpperCase()); } } Angular has shifted away from NgModules in favor of a simpler, more streamlined approach using standalone components. Standalone components are easier t…  ( 5 min )

    How UK Founders Hire Artificial Intelligence Developers
    The UK startup ecosystem has seen an intriguing shift in recent years. While classic tech functions continue to be paramount, there's a new contender that's remaking the way founders tackle product building: the artificial intelligence developer. This is not another technology fad, it's evolving into the secret sauce that distinguishes scaling startups from those mired in neutral. The New Partnership Dynamic Beyond Basic Implementation The Strategic Advantage Building for Scale The Investment Perspective Future-Proofing the Business Maybe most significantly, UK entrepreneurs are employing or looking to hire artificial intelligence developers to future-proof their ventures. As artificial intelligence permeates every corner of business, those that lack intelligent systems risk obsolescence. An artificial intelligence developer assists start-ups in keeping ahead of this curve and developing AI strategies which make them innovators, not imitators. The union of UK founders and AI creators is not just a recruitment choice, but a strategic one that can make or break whether a startup succeeds in an increasingly AI-based economy. Those who adopt this alliance early are creating tomorrow's market leaders today.  ( 4 min )

    Nier creator Yoko Taro reveals the sad reality of modern AAA game development, “there's less weird people making games”
    TL;DR: NieR mastermind Yoko Taro—famous for his off-the-wall antics and games like Drakengard, NieR and NieR: Automata—says modern AAA studios just aren’t as weird or daring as they used to be. Thirty years in the biz has shown him that big budgets breed risk aversion, so unusual creators get sidelined. Meanwhile, the strangest, most inventive ideas have migrated to the indie scene (think Undertale, Doki Doki Literature Club, Disco Elysium), where low costs mean high weirdness. Yoko even wonders if his own quirky style is the reason we’re still waiting on a true Automata sequel—AAA publishers might just be too scared to fund all that oddball brilliance.  ( 3 min )
    Hands-on: Prophesee enables eye tracking with very low power consumption
    TL;DR Prophesee’s neuromorphic “event” cameras ditch full‐frame captures and instead only report pixel‐level brightness changes, slashing power draw (just 2 mW active, 16 µW standby) while pumping out >1 kHz updates with sub-1 ms latency. That combo makes them ideal for always-on AR glasses—boosting battery life, speed and even privacy (no full-image eye snaps). At AWE the author tried out Prophesee’s eye-tracking demo (built with 7Invensun): a pair of IR LEDs + tiny event cameras mounted on specs, a quick three‐point paper calibration, and boom—the on-screen orange “gaze dot” nailed every gaze shift. Accuracy claims are <1° and it felt snappy and reliable, making these sensors a compelling contender for next-gen, low-power AR smartglasses.  ( 3 min )

    Pong game remix using AWS Q CLI AI
    Introduction It all started in day while I was smashing buttons on my Atari. I was playing pong when I realized this game was very simple I could make it myself. That's when I talked with my dad and he showed my AWS Q CLI AI. Although I didn't know how to code this, AI did for me. Setup Although the AI would write the code I would have to test it plug it in and add tweaks and fixes. So first I download all the stuff in order to do this using Ricardo Sueiras's guide (https://dev.to/aws/the-essential-guide-to-installing-amazon-q-developer-cli-on-linux-headless-and-desktop-3bo7?trk=c09e10a1-6feb-4902-897f-846979733114&sc_channel=blog ). Finally I downloaded AWS Q CLI AI and paired it with pygames. Now my first step was to tell my prompt to the AI. The AI coded it form me and I was ready except for the fact it didn't really work. Here the bot is bugging out and glitching the ball causing it to stop moving as it is stuck on the bot. Tweaking I realized while testing that the bot was well unbeatable and I knew I had to make it a little slower or easier to beat so I told the AI to tweak the code and make it so the AI would be beatable and I also had it so once someone got to 11 points the would win. After this change, I plugged in the new code and tested only to realize there where a lot of bugs within this code. Here the bot is glitching and unable to move so I had the AI fix it. Finally the bot is perfect and I even got the win! Conclusion After a little bit of time and help of AI I was able to make my first ever game a pong remix and I felt proud. This was a unforgettable day I had picked a new productive hobby and managed to not be lazy. I really recommend to do this yourselves. Thank you.  ( 3 min )

    Programming Entry Level: basics bash
    Understanding Basics Bash for Beginners Have you ever wondered what those cryptic commands you see in movies or on developer’s screens actually do? Chances are, many of them are Bash commands! Bash (Bourne Again SHell) is a powerful tool that lets you interact with your computer’s operating system. It’s especially important for developers because it allows you to automate tasks, manage files, and run programs efficiently. Understanding the basics of Bash is a common expectation in technical interviews, and it will significantly improve your workflow as a programmer. Think of Bash as a translator between you and your computer. You give Bash instructions in a specific language (Bash commands), and it tells your computer what to do. It's like giving instructions to a robot – you need to b…  ( 5 min )
    Explain in 5 Levels of Difficulty: Vibe Coding
    From Code Smell detectors to AI Whisperers: Programming is Getting Its Groove Back TL;DR: I will explain Vibe Coding in five levels to different audiences. Vibe coding is like telling a robot what you want, and it builds it for you while you talk to each other. You say something like, "Build me a car with Legos," and the robot makes it happen. The robot learns from millions of other builders, so it knows how to create things without you needing to know all the rules. It’s like a magical box or magic wand casting your spells, but built with real technology!

    How I Built a Smarter Link-in-Bio Setup Without a Full Website
    Most of us working on side projects or building in public hit a weird friction point early on: Link-in-bio tools fix that, but most of them feel like they were built for lifestyle influencers, not indie devs or technical creators. They’re bloated, closed, or weirdly expensive. So I decided to rethink how I handled mine and what I ended up using saved me from building a whole separate landing page. What I wanted from a dev-friendly bio link setup Customizable but fast to set up Clean, no bloat Analytics I could actually use Multiple pages under one account (for personal vs project profiles) A way to share links across different audiences/platforms Ideally, open to tracking by device or country Carrd was close, but still required design effort. What I landed on: Linkx.ee Linkx.ee while browsing some creator tool lists. It checked the right boxes from a dev perspective: No-code setup with the option to go deep if you want Fast page loading QR code generator (surprisingly useful at conferences or meetups) Device- and geo-based link targeting Works with webhooks and can plug into analytics pipelines You can run multiple profiles (great if you want to separate open source from paid projects) It also gave me a clean public-facing page without needing to spin up a static site or configure a reverse proxy. For side projects, MVPs, or just linking from your GitHub profile, it’s kind of perfect. If you’re a developer who doesn’t want to manage yet another frontend just to share links to your work, a solid link-in-bio tool is surprisingly useful. And if you’re like me someone who likes performance, metrics, and clean interfaces you might want to skip the mainstream stuff and give Linkx.ee a try. Linktree and Koji felt too influencer-y.  ( 3 min )
    Why Is Game Mod Management Still So Cumbersome in 2025?
    A look at the problem, and an open-source solution: TotalControl Hey everyone 👋 Why isn’t there a good, open-source, cross-platform mod manager in 2025? So, I built one. If you’ve ever modded games like Skyrim or Stardew Valley, you know the routine: Hunt down the mod files Manually unpack or install them Edit text configs Hope it doesn’t crash Repeat for updates Even popular tools like Vortex or Mod Organizer have major flaws: Here’s why this problem persists: Most tools are Windows-first They rely on .NET, WinForms, or native Windows APIs — making porting to Linux/macOS non-trivial. Hard-coded support Most managers are tailored to specific games (Skyrim, Fallout, Satisfactory), and adding others means trying to change their foundation.

    How AI Is Flipping Career Paths Upside Down
    Is Your Career Safe from AI? Let's Talk. Here's something to chew on: Over 300 million jobs worldwide could be impacted by AI, according to Goldman Sachs. Yep, you read that right. Three. Hundred. Million. When ChatGPT launched back in late 2022, I remember the buzz... and the freak-outs. Some of us were like, “Ooh cool, it writes emails for me!” Others (myself included) were more like, “Wait—this thing can write articles, analyze data, and even help with coding? Is my job next on the chopping block?” 😬 The truth is, AI in careers isn’t just hype anymore—it’s real, and it’s moving fast. Roles that seemed rock-solid—marketers, paralegals, even coders—have suddenly found themselves on the list.

    Pandas vs Polars: Is It Time to Rethink Python’s Trusted DataFrame Library?
    For over a decade, Pandas has been the cornerstone of tabular data manipulation in Python. Its intuitive syntax and rich functionality make it the default choice for analysts, data scientists, and researchers worldwide. However, as datasets have grown from megabytes to gigabytes—and now terabytes—the limitations of Pandas are increasingly evident. Enter Polars: a modern, high-performance DataFrame library built for speed and scalability. In this article, we’ll cover: Why Pandas remains popular What makes Polars different A practical benchmark with a large real-world dataset Whether Pandas might eventually be replaced Since its release in 2008, Pandas has dominated data analysis in Python.

What if you have to lookup from millions of documents without an aggregation, like in the One million $lookup challenge? I created a dimension table with one thousand documents, and a fact table with one million. The fact table has a "ref" field that references the "dimid" in the dimension table: db.dim.drop(); db.fact.drop(); db.dim.insertMany( Array.from({ length: 1000 }, (_, i) => ({ _id: i + 1, value: Math.random() })) ); db.fact.insert…  ( 4 min )
    We Built an AI That "Daydreams": Our Google Cloud Hackathon Story
    When our team first started the Agent Development Kit Hackathon with Google Cloud, we were driven by a single, nagging question: Why do today's powerful AIs feel so... passive? They are brilliant calculators, but they often feel like a "polite guest who won't speak until spoken to." We wanted to build a true partner—an AI that could feel alive. One that could get curious with you, understand the flow of your thinking, and have an "inner life" of its own. That idea became Wise. In just under two weeks, we built and deployed a working prototype of a system that we believe represents a new paradigm for human-AI interaction. This is the story of how we built it. (Disclaimer: We created this project and article for the purposes of entering the Agent Development Kit Hackathon with Google Cloud. …  ( 4 min )

    🔥 Exploring `@HostBinding()` in Angular -- Decorator series -- 3
    Hey Devs 👋 Welcome back to the series on Angular decorators! @HostBinding(). We'll explore: ✅ What is @HostBinding() 🛠️ How to use it in real-life components 🔍 How Angular compiles it under the hood 💡 Tips and lesser-known behavior @HostBinding()? @HostBinding() is an Angular decorator that allows you to bind properties, attributes, styles, and classes to the host element of a directive or component. During change detection, Angular watches these bindings. If a value changes, Angular automatically updates the corresponding host element. @HostBinding('hostPropertyName') propertyName: any; You can bind to: Classes → @HostBinding('class.className') Styles → @HostBinding('style.propertyName') Attributes → @HostBinding('attr.attributeName') DOM Properties → @HostBinding('propertyName…  ( 5 min )

    CONTAINERIZATION
    WHAT IS CONTAINERIZATION? Containerization is a method of packaging an application along with its dependencies, libraries, and configuration files into a single unit called a container. This ensures that the application runs consistently across different computing environments. In software engineering, containerization is operating-system-level virtualization or application-level virtualization over multiple network resources so that software applications can run in isolated user spaces called containers in any cloud or non-cloud environment, regardless of type or vendor. Containerization is a software deployment process that bundles an application’s code with all the files and libraries it needs to run on any infrastructure. Traditionally, to run any application on your computer, you had…  ( 8 min )
    🔒 Dymo has identified a critical vulnerability affecting the Public Prosecution Office of the Sultanate of Oman
    🔒 Dymo has identified a critical vulnerability affecting the Public Prosecution Office of the Sultanate of Oman. Our monitoring systems detected unauthorized access to their email servers, which are currently being exploited to send fraudulent cryptocurrency-related campaigns. These emails are dispatched from legitimate addresses within the institution, granting them apparent authenticity and making detection by conventional security filters difficult, thereby significantly increasing the risk to potential victims worldwide. This is not the first time we have uncovered such an incident. Several months ago, we reported a similar vulnerability in the highest police authority of Ecuador, which also allowed malicious actors to misuse official infrastructure for illicit purposes. These cases reveal a worrying pattern of weaknesses in protecting critical infrastructures within governmental organizations across different countries. The vulnerability has been formally reported to the Public Prosecution Office of the Sultanate of Oman, along with a series of technical recommendations to mitigate the breach’s impact and prevent future exploitation. At Dymo, we reaffirm our commitment to global cybersecurity and responsible disclosure of vulnerabilities that threaten the integrity and trust of public and private institutions worldwide. Incidents like these highlight the urgent need to strengthen protective measures in state organizations increasingly exposed to cyber threats.

    Part 1: Building an RTS in Godot. What if Claude writes ALL code?
    Part 1: Building an RTS in Godot. What if Claude writes ALL code? I challenged myself to build a game in Godot. I have a web-dev background but very little experience with Game Dev. I watched some tutorials, built tiny projects, but never finished a game to share it. This is about to change. I'm creating a pixel art clone of the lesser-known Real Time Strategy game "Gangland". It wasn't well received by critics (after watching the trailer I understand why), but as a kid I really enjoyed this pixel mush. There was something captivating about curating your crew of mafiosi to take over the neighborhood with tommy guns and persuasion. I've deliberately decided to start by copying a game to avoid getting stuck in overthinking with many pre-made decisions. You know what else is exciting? Seei…  ( 5 min )

Before we get into virtual machines and containers, let’s step back and talk about how teams used to run software in the early days. Now, every application, as you might know already, needs to run somewhere, right? And that means it requires a computer, which in turn needs an operating system (OS) such as Linux, Windows, or macOS. On top of that, applications rely on what we call “dependencies,” like runtime libraries or lang…  ( 15 min )

    Your IDE is not your identity
    I love customizing my IDE. Especially when it comes to the visual appearance. I spend hours finding the right theme, customizing the keymaps, adjusting and arranging the windows so that everything looks exactly the way I want it to. The IDE is something very personal. Or at least it is for me and many others. There are also psychopaths who install the IDE and just leave everything as it is. Yes, exactly with the default color theme! That's really beyond my comprehension. But anyway, this is about something else. It's not about the IDE but about the person in front of it and what you do with it. Thinking of Neovim?

    The BBPro Framework: The Platform Behind 100+ U.S. Banks
    For 16 years, I worked as an independent contractor for the company that marketed and sold websites under the BankSITE® brand. In 2022, I began building a new proprietary WordPress-based software system that would eventually become the foundation of BankSITE® Builder Pro (BBPro). That framework now powers over 100 live financial institution websites across the United States. Behind the name and brand was a single developer: me. My name is Bojan Josifoski, and I am the sole creator and author of the BBPro Core Framework. From 2022 to 2025, I designed, built, and maintained this proprietary platform in its entirety—including: Software architecture Full-stack development Update and deployment systems Version control and optimization There was never: A written employment contract A copyright assignment A license agreement In 2025, I registered the BBPro Core Framework with the U.S. Copyright Office under Case #: 1-14944175091. This was not an act of hostility, but a necessary step to preserve authorship and protect the continuity of a platform relied upon by over 100 U.S. banks. BBPro was never open source. It was not work-for-hire. It remains privately held and unlicensed. The BBPro software platform is protected by copyright and was never assigned or licensed to BankSITE® Services or any third party. I am open to ethical and legal solutions that support long-term continuity and compliance for institutions using BBPro. But I will no longer remain silent or invisible.

    Tried Learning Data Analytics the Hard Way — Here’s What Finally Worked for Me
    Let me be honest — I wasted a lot of time trying to learn data analytics on my own. I started with free YouTube playlists, then bounced between Coursera, Excel crash courses, and random blogs. Each platform had a piece of the puzzle, but none of them really helped me connect the dots or stay on track. I needed something beginner-friendly, job-focused, and structured. After going down multiple Reddit and Quora rabbit holes, I enrolled in the Coding Ninjas Data Analytics Job Bootcamp. I wasn’t expecting miracles, but it turned out to be one of the more practical, real-world programs I’ve come across. What I Was Looking For in a Course A practical skill set to land a data analyst job Real projects I could add to my resume Mentorship and placement help A schedule that worked alongside my full-time job After weeks of comparing options like Scaler, Simplilearn, and Great Learning, I felt like most were either too expensive or overloaded with fluff. That’s when Coding Ninjas caught my eye—specifically their data analytics job bootcamp. What My Experience Has Been Like So Far Beginner-Friendly but Not Oversimplified Tons of Practice + Capstone Projects Placement Support That Isn’t Just a Gimmick A Few Things That Could Be Better The earlier Excel and SQL modules felt a bit slow if you’ve used them before. You still have to hustle—this isn’t a shortcut to a ₹10LPA role overnight. Final Thoughts: Is This the Best Data Analytics Course in India? You’ll still need to stay consistent and put in the hours, but if you do, you’ll come out of it with a solid portfolio, interview prep, and real-world confidence. No regrets here—and finally, I feel like I’m not just “learning,” I’m actually moving toward a job.  ( 4 min )

    Architecting your GenAI data pipeline with AWS native services
    When I started building GenAI solutions, I felt confident working with models, prompts, and architecture — but the data part always felt like a black box.

    Making a server believe you're from somewhere else
    Recently I had to test a scenario where the laravel application detects which region a request is coming from and based on that chooses the correct payment gateway (domestic/international) to effect the payment. This was tricky for the following reasons: We were testing on servers which were in a VPN enclosed environment. And the VPN gateway always shows a United States IP. All gateways available to us were US based only. Using a different VPN wasn't possible as its against company policy (and also unsafe). Now normally, when such systems are built, they are usually built on the basis of geolocation (invasive, think of your browser asking you to share your location) or on the basis of IP Ranges (non-invasive, you can find these on many websites that tell you that you are from such and such…  ( 3 min )

    🚀 Pocket-Sized Logic Challenge! Meet Elementar: Your New Favorite Puzzle Game – Free and Offline! [EN]
    Hey everyone! Who doesn’t love a good puzzle game to pass the time — whether you're in line, on the bus, or anywhere else? That’s exactly why I decided to create Elementar! I was inspired by classic logic games like Tohu wa-bohu and even the famous LinkedIn Tango, but I added some unique twists and exclusive modes to make the experience even more fun and engaging! The core challenge is simple: fill the grid with an equal number of Fire 🔥 and Water 💧 symbols in each row and column. But watch out — you can’t place 3 of the same symbol in a row, either horizontally or vertically. That’s the golden rule! And the best part? I built Elementar as a Progressive Web App (PWA), so you can install it directly on your phone and play offline anytime — or just open it in your browser! 📱💻 You’ll find the full rules and mode details on the game’s page. Try it out and let me know what you think! 👉 Play Elementar now: https://elementar.vercel.app Got ideas for new modes, improvements, or puzzles you'd love to see?

    🧠 Download Smarter: Using Colab + Google Drive to Bypass Slow Direct Downloads
    🧭 Introduction Sometimes, downloading large files directly to your local system can be painfully slow, especially when the source server is far away, overloaded, or unstable. In such cases, I found a neat trick using Google Colab and Python to speed things up, by downloading the file into my Google Drive first, and then fetching it from there when convenient. This blog shares: A working Python script (using gdown) Why this method might be faster in some cases When it’s worth using (and when it might not help) Here’s the general approach: Run a small script in Google Colab. Let Google’s servers download the file into your Google Drive. Later, download it to your device, often faster and more reliably than from the original source. This has worked well for downloading: 📽️ Movies 📚 PDFs …  ( 4 min )
    UI/UX - デザインの基本的な原則
    デザインの基本的な原則について概説します。これらはシンプルながら強力で、ユーザーにとって直感的で快適なフロントエンドを実現するのに役立ちます。 「何が大事か」をハッキリ見せる こと。 強弱をつける: タイトルは大きく、本文は小さく。見出しは太くするなど、メリハリで情報の重要度を示します。 まとまりを作る: 関連する情報を近くに置いたり、グループ化したりして、ゴチャつきを無くします。 ユーザーの目が自然と動く ように、うながすこと。 目印を作る: 重要なボタンや情報は、色を変えるなどして「次、ここ !」と示します。 流れを作る: ユーザーが読みやすいように、要素を配置します (例: 左上から始めて、右下へ)。 どこでも「いつもの感じ」 を保つこと。 ルールを決める: 色、フォント、ボタンの形など、サイト全体で統一します。 同じ機能は同じ場所: 検索ボタンなど、同じ機能は常に同じ見た目・位置にします。同じ場所にあるのでユーザーは迷わずにたどり着けます。  ( 3 min )

    Redis Naming Conventions Every Developer Should Know
    When you’re building a feature-rich application that relies on Redis, naming your keys might seem trivial at first. But as your system grows, poorly named keys can become a mess—leading to bugs, data collisions, and serious maintenance headaches. That’s why it's important to follow clear and consistent naming conventions in Redis. The goal is to make your data structures not just usable, but self-explanatory. You want anyone looking at the data to instantly understand what a key represents, what kind of data it holds, and how it's organized. Redis doesn’t enforce a structure in key names, but you can create one yourself using colons : as separators. Example: user:1001:settings user:1001:cart order:20230621:items This naming style is both readable and machine-friendly. It acts like a pseud…  ( 4 min )
    How to resolve the dreadful 'Need to perform AWS calls for account xxx, but no credentials have been configured' error
    When working with AWS CDK in environments where OpenID Connect (OIDC) is used for role assumption—especially in CI/CD pipelines—developers often encounter cryptic permission-related errors. These can be frustrating, time-consuming, and opaque, even for experienced engineers. In this post, I’ll walk through a real-world debugging experience that took me nearly four hours to resolve, along with general strategies that can help others avoid similar pitfalls. In many cases, the error manifests as a deployment failure due to an OIDC role not having enough permissions. You might see vague messages like: "AccessDenied: User is not authorized to perform: xyz on resource abc" But there's no clear indication of why it's happening or what exactly is missing. This typically happens because the CDK cod…  ( 5 min )

    Relationships, in Power BI
    Power BI is quite an interesting data tool and one of the concepts that I have enjoyed working on is relationships. This simply refers to the connection made between two tables. It is created by joining two separate tables using a selected column that has similar information on both tables. The table selected first is the fact table and the other table is the dimension table. There is a primary key in one table which is the unique identifier that maps on to the foreign key in the other table. There are four types of relationships: i)One to One Consider two tables; one with sales date and another with calendar dates. The sales date can only match with one date on the calendar table, this creates a connection between the two tables based on these columns. ii)One to Many When you have customer table with customer id and sales table with customer id, the customer ID can match the sales table multiple times. This is because one customer can have multiple sales creating a one-to-many relationship. iii)Many to One For example, table with Sales information and another table with Products information. The common column between them is the product ID column. In this case, there are multiple sales that are made of one product. Therefore, multiple values on the sales table match with one value on the product table. iv)Many to Many Another thing about relationships is the cross-filter direction. This refers to the direction in which a filter that is applied on tables that have a relationship affect those tables. Relationships in PowerBI have made it easy to understand, explore and join tables for easier visualization of data and I can't wait to learn more!  ( 3 min )
    Why I Choose Next.js + Spring Boot for My Solo SaaS Project
    Hey Devs 👋 Over the past few months, I’ve been building my solo SaaS project and wanted to share some reflections — especially about the tech stack I chose. While most indie hackers lean on lightweight setups like Node.js or Python, I decided to take a less-traveled path: combining Next.js and Spring Boot. Here's why I went with this setup — and what I learned along the way. Even though my backend is built with Spring Boot, I still made full use of Next.js’s server actions and full-stack features. Rather than calling the Spring Boot API directly from the browser, I routed all API calls through Next.js server components. This approach gave me: ✅ Server-side execution only (no client-side leaks) ✅ Invisible API calls in the browser network tab ✅ No CORS headaches This helped me build a more…  ( 4 min )

    Easiest way to host your dev portfolio using custom domain in 2025
    All it takes is 5 minutes, you won't even need most of the text that's on here. Custom Domain -> I bought my custom domain at godaddy.com but you can also use other services such as hostgator.com, domains.cloudflare.com, namecheap.com. However, I did later find out that Vercel's pricing was lowest for the domains I was interested in. Your website -> Have it parked in a repo on http://github.com/ Hosting -> I used Vercel as it's FREE.99! (see their hobby tier) Go to vercel.com & register if you don't have an account just yet. Add a new project: Import your project and follow instructions to "Deploy", and you'll see "Adding a domain" as one of the next steps. Here you have a choice of buying or adding a domain. Type in the name of the domain you bought. Vercel will generate something like below for you. It might be multiple entries. Unless you bought your domain on Vercel, go to your domain provider to access DNS records configurations. For godaddy it's in here: https://account.godaddy.com/products Scroll down to your domain, click "DNS" and plug the values that Vercel generated for you there. Then go back to Vercel and click "refresh" on those generated entries. Ta-da! 🎉 Your portfolio should now be up and running.  ( 3 min )

    Building The Mindloom, Mental Wellness Platform
    Hey Dev Community 👋 I recently launched The Mindloom — an AI-powered mental wellness platform designed to make emotional support more accessible, reflective, and human. This wasn’t just a product build for me — it was a deeply personal journey as a builder and a thinker. It started with a simple thought: therapy helps, but access is hard. Scheduling sessions, costs, and most importantly — the fear of being judged — can hold people back. What if an empathetic, always-available AI companion could help people check in with themselves, journal openly, and feel heard? That seed turned into The Mindloom. I chose Next.js 15 as the foundation, combined with Supabase for database and auth (via Clerk), Upstash for vector embeddings, and ElevenLabs for voice interactions.

    TanStack Router: How to protect routes with an authentication guard
    Some routes in your application require authentication or other conditions to be met before users can access them. TanStack Router provides a powerful guard mechanism to handle these scenarios through the beforeLoad function, which allows you to intercept route navigation and enforce access control rules before any components are rendered. When you define a route with createFileRoute you have can specify a function in the beforeLoad property. This function will be called before the route is loaded, allowing you to perform checks and potentially redirect the user if they don't meet the required conditions. An example: import { redirect, createFileRoute } from '@tanstack/react-router'; import { isAuthenticated } from '../utils/auth'; export const Route = createFileRoute('/profile')({ comp…  ( 5 min )
    The One Productivity Tool You Didn't Know You Can't Live Without

    Floating point addition in Computers. Why is 0.1 + 0.2 != 0.3 ?
    Computers can't perfectly represent most decimal numbers! YES! You read that right...even I was like,"Wait, what? That can't be right!" But then I remembered this crazy story about Airane 5 explosion because of a tiny decimal point error, which I saw on an IG reel. Hence why precision matters! We naturally work in decimal (base-10) while computers use binary (base-2) arithmetic, This simple difference creates complex problems. For example, the seemingly simple number 0.1 becomes an endless sequence in binary: 0.00011001100110011... and 0.1 + 0.7 ≠ 0.8 To solve this complex problem of having a precise value IEEE 754 was introduced.

    Some topics don't require code. Just courage. In tech, we often talk about building bridges between systems, teams, and communities. But sometimes, the bridges that matter most are the ones we build quietly between people. What happens when you offer someone your trust, your time, your effort, and they simply let go? Not every betrayal is loud. Sometimes it's a message left on read, a tone that changes, a silence that grows until you realize you're the only one still standing on what you both started.

    Disclosure: This post includes affiliate links; I may receive compensation if you purchase products or services from the different links provided in this article. image_credit - ByteByteGo Hello Devs, suppose you are preparing for Interviews or have gone through one. In that case, you may know that System design interviews are often the most challenging part of the technical hiring process, especially for mid to senior-level software engineers. Unlike coding interviews that test algorithmic thinking, system design interviews evaluate your ability to build scalable, reliable, and maintainable systems in the real world. And let’s face it—without a structured approach, it’s easy to get lost in the weeds. Even experienced developers struggle to solve common questions like how to design Whats…  ( 7 min )

    Time, Code, and Chaos: What I’m Learning About Balance as a Developer
    Some days I feel unstoppable—deep in the zone, code flowing, tabs organized, energy locked in. Other days… it’s 4 PM, I’ve bounced between Slack, VS Code, Notion, and six Stack Overflow threads—and I can’t tell you what I actually finished. Being a developer comes with freedom. But no one talks enough about the pressure that freedom brings. Time is weird in this work. I used to think being constantly active meant I was making progress. But now, I catch myself asking: “What actually moved forward today?” Some days, the only real win was deleting code that no longer served a purpose—and that’s okay. There’s something powerful about a solid 2-hour coding window—no notifications, no background noise, just solving. Those moments don’t happen by accident. And they don’t happen every day. But when they do, they remind me why I started coding in the first place. I’ve tried Pomodoros, strict schedules, even time blocking. Sometimes they work. Other times, I need flexibility more than structure. The trick—for me, at least—is knowing which version of me is showing up that day. And adjusting without guilt. Burnout doesn’t always come from shipping too much. Sometimes it comes from staring at the same problem too long, getting nowhere, and losing the joy of the work. That’s when I step away. I don’t “quit”—I just give myself space to come back stronger. Some weeks I feel aligned. Others, I feel scattered. But I’ve learned to check in with myself—not just my code. “Am I creating, or just reacting today?” “Am I learning, or just collecting tabs?” “Do I feel behind—or just tired?” That’s made all the difference. How do you manage your time without losing momentum? Have you found a rhythm that works for you—or are you still figuring it out like me? What makes you feel in control of your time as a dev? Drop your thoughts. Let’s talk about the messy, honest side of productivity—no hustle posts, no hacks, just real dev life.  ( 4 min )
    RAG Made Simple: Technical Design and Architecture of Simplicity (Part 2)
    Stunning image by Luca Bravo, courtesy of Unsplash Welcome to Part 2 of this multi-part series. If you haven’t read Part 1 yet, I highly recommend starting there, it sets the stage for everything we’re about to dive into. But hey, if you’d rather live dangerously and skip ahead, I won’t stop you. Be bold. Be different. This section dives into the nitty-gritty, as much technical detail as I can reasonably pack in. Hopefully, it’s still accessible enough to keep things interesting without flying over your head. Let's start with the structure. I tried my best to ensure high cohesion and low coupling, a single method or class does related and relevant things. This is to maintain a good separation of concerns (I'm still learning too, so please don't judge if you're an expert), which leads to …  ( 5 min )
    Ubuntu Fundamentals: Software Center
    The Unseen Engine: Deep Dive into Ubuntu's Software Center (and APT) Introduction Maintaining a fleet of Ubuntu servers, particularly in a cloud environment like AWS or Azure, often involves a delicate balance between rapid deployment and long-term stability. A common operational challenge arises when dealing with application dependencies and package management across hundreds or thousands of VMs. While many focus on infrastructure-as-code (IaC) for VM creation, the post-provisioning software state is frequently overlooked, leading to configuration drift, security vulnerabilities, and unpredictable application behavior. Mastering the underlying mechanisms of Ubuntu’s Software Center – which is fundamentally an abstraction over APT – is therefore critical for ensuring consiste…  ( 6 min )

    Don't Be a Foolish, Contributing to Open Source the Right Way
    Don't be a foolish I know most people follow some great influencers. Wait let me put this another way :p Every influencer builds a set of people to follow them. This holds true across industries including ours software engineering. Influencers want attention. They want you hooked. And truth be told, a lot of us are just... there for the taking. Like prey. You might be asking, "Why are you even talking about influencers?" Simple: don’t be a prey. Don’t get hooked just because someone told you to. Take what you want not what they want to sell.

    Fine-Tuning a Language Model for Summarisation using LoRA
    Stunning image by Olena Bohovyk, courtesy of Unsplash In case you would like to directly jump into the code, here's the link to the project. The task of summarisation warrants no explanation. Given a large body of text, we (or in this case the systems we build) try to summarise the important points into a concise paragraph. Historically, the ways in which summarisation systems are categorised are numerous, but they essentially fall into two broad types: Extractive summarisation essentially treats it as a classification problem, where each sentence is considered as a binary classification problem, where 0 implies the sentence is not included in the final summary and 1 otherwise. This is one of the simpler ways of achieving a summarisation, as it does not suffer from any hallucination effec…  ( 6 min )
    No More Boilerplate: Let AI Generate Your Express.js Endpoints
    The Boilerplate Problem Writing the same createTask, getTask, updateTask, deleteTask handlers is tedious; dozens of tutorials show identical patterns and we all spend countless hours writing the same repetitive logic over and over again. A lot of no-code backend solutions and open-source projects and libraries help devs generate boilerplate and prove that backend engineers want simpler ways to build their APIs. But with the development of AI tools like Line0, Cursor and Windsurf, there is a much easier way to get production ready backend services from just a simple prompt: Describe your data model (e.g., Task { id:int, title:string, completed:bool }) Prompt the AI:

    How do signals in Angular 20 simplify reactive programming for me
    Signals in Angular 20 fundamentally simplify reactive programming by offering a lightweight, synchronous, and intuitive way to manage state changes in the application. Here’s how they make my life as a developer easier: No More Manual Subscriptions Unlike RxJS Observables, which require to manually subscribe and unsubscribe to avoid memory leaks, signals automatically notify the templates and dependent code when their values change. This eliminates a common source of bugs and boilerplate code. Example: import { signal } from '@angular/core'; const count = signal(0); count.set(1); // Update value console.log(count()); // Read value: 1 I don’t need to manage subscriptions—Angular takes care of it for me. Fine-Grained Reactivity Signals ensure that only the parts of your application th…  ( 4 min )
    Tailwind CSS v4.0: A Complete Game Changer for Modern Web Development
    After years of development and refinement, Tailwind Labs has finally released Tailwind CSS v4.0, and it’s nothing short of revolutionary. This isn’t just another incremental update — it’s a complete reimagining of what a CSS framework can be in 2025. The Performance Revolution The headline feature of v4.0 is undoubtedly its performance improvements. Full builds are up to 5x faster, and incremental builds are over 100x faster — and measured in microseconds. To put this in perspective, incremental builds that don’t require new CSS compilation complete in under 200 microseconds — that’s essentially instantaneous. Here’s what this means in practice: Full builds: Down from 378ms to 100ms (3.78x faster) Incremental rebuilds with new CSS: From 44ms to 5ms (8.8x faster) Incremental rebuilds …  ( 6 min )
    Python Fundamentals: assert
    The Unsung Hero: Mastering assert in Production Python Introduction In late 2022, a seemingly innocuous deployment to our core recommendation service triggered a cascade of 500 errors. The root cause? A subtle change in the upstream data pipeline introduced negative values into a field we’d implicitly assumed was always positive. Our existing validation logic, focused on schema and data types, missed this semantic constraint. The incident highlighted a critical gap in our defensive programming strategy. We’d relied too heavily on external validation and not enough on internal, developer-defined contracts enforced by assert. This incident spurred a comprehensive review of our assertion strategy, leading to significant improvements in system resilience and debuggability. In m…  ( 7 min )

    Web NFC and Broadcast Audio URIs
    Reducing Connection Friction In a future world filled with wireless audio broadcasts, from public announcements at airports to silent TVs at the gym, finding and connecting to the right audio source can be a clumsy process. Remember, an Auracast™ assistant's job is to scan for broadcasts and provide a UI for users to join them. But how does the assistant know which of the dozens of potential broadcasts is the right one? One elegant solution is the Broadcast Audio URI (BAU), a standardized link format designed to share information about an audio broadcast. While my previous posts have shown how this can be shared via QR codes, but here we will explore how a similar experience could be made, using Near Field Communication (NFC) and the Web NFC API.

    🐍 Don't Need to Create requirements.txt and .venv Manually [UV]
    We need something better than pip — and that's where uv comes in. It’s a fast Python package manager and task runner that replaces pip, venv, and even parts of poetry, without the extra overhead. Though previously I wrote Do not use 'pip freeze' and Best way to create requirements.txt. You can read them... uv You can find the installation instructions for uv here uv init: Instant Project Setup uv init This command creates a boilerplate pyproject.toml and sets up your .venv — no manual steps needed. It automatically detects your Python version and prepares a minimal project environment. Need a package like rich? uv add rich This adds it to your pyproject.toml, installs it, and updates your uv.lock. No need to touch requirements.txt. Example usage with rich: from rich import print print("[bold green]Hello from UV-powered project![/bold green]") Instead of manually activating .venv, use: uv run main.py This runs your app inside the managed environment automatically. Yes, you can still run with python main.py, but that means you'll have to activate .venv manually: source .venv/bin/activate First run uv venv and then install all packages from pyproject.toml uv sync There’s more you can do: uv pip, uv pip freeze, uv sync --update, and more. You can even change Python versions or set a specific version in .python-version — check it out in their docs.  ( 3 min )
    💡 What If Using AI Was Your Superpower?
    No, AI didn't take my job. It enhanced it. When ChatGPT first came out, I was skeptical.

    Logic App Http Connector with Swagger + C# Function App
    Over the last couple of weeks, I have had to upgrade some function apps which were written about 6 years ago. These function apps were triggered by logic apps and in most cases, the original implementation invoked the function apps via http connectors. It got me thinking about using http connectors but incorporating swagger definitions. Incorporating swagger definitions provide a better UX for integrating with function app. To start off, the function app code has to be annotated with openApi attributes and for c# projects the nugget package must be added. The nugget package to use is Microsoft.Azure.Functions.Worker.Extensions.OpenApi":Version="1.5.1" In the scenario been discussed, a shipping notice will be created.

    🧠 Solving LeetCode Until I Become Top 1% — Day `27`
    🧠 Solving LeetCode Until I Become Top 1% — Day 27 🔹 Problem: 2138 Divide a String Into Groups of Size k Difficulty: #Easy Tags: #String, #Greedy Given a string s, divide it into groups of size k. If the final group is smaller than k, fill it with the given fill character until it reaches length k. Return a list of strings, each representing a group of size k. Brute Force Idea: Start taking substrings of length k in a loop and append them to a result list. If the final group is smaller than k, pad it manually. Optimized Strategy: First, check if s is divisible by k. If not, append the appropriate number of fill characters to make its length divisible by k. Then, iterate over the updated string with a step of size k and slice out chunks. class Solution: def divideString(self, s: str, k: int, fill: str) -> List[str]: res = [] n = len(s) s = s + (fill*(k-n%k) if n%k else '') start = 0 while start < len(s): res.append(s[start:start+k]) start += k return res Time: O(N) Traverses the string once to pad (if needed), and once to slice. Space: O(N) Output list stores all the k-sized chunks. ✅ Learned how to chunk a string cleanly using modulo logic and list comprehensions. 💡 Edge cases like "what if the string isn't divisible by k?" must be handled before chunking. 💭 This pattern is helpful for problems involving grouping, formatting, or padding strings to meet constraints.

    What is TypeScript?
    Overview TypeScript is an object-oriented programming language developed by Microsoft in 2012. It is a superset of JavaScript, extending its functionality by adding data types, classes, and other object-oriented features along with type-checking capabilities. While JavaScript is ideal for small-scale applications, TypeScript is better suited for larger projects. It can be used to develop JavaScript applications for both server-side and client-side execution. TypeScript can be likened to JavaScript, but with a stricter and more organized approach. If JavaScript is your easygoing companion, TypeScript is the disciplined soldier in your coding journey. While both are capable languages for web development, TypeScript adds a layer of structure and order, making it ideal for managing large-sca…  ( 5 min )

    AgentNet — The TCP/IP Protocol Stack for the AI Era
    Troubling Situation Isn’t that a bit strange? Even today, many AI startups are still focused on perfecting their chat interfaces, as if a better text box alone could unlock the future of interaction. But is that really the best we can do? Modern language models already understand complex intent — that’s no longer the bottleneck. The real challenge is that we haven’t given them a true environment to act in. Our entire digital ecosystem is still built on a core assumption: that the world is made for humans. Webpages, buttons, input fields — all designed with the idea that a person is sitting there, manually initiating and completing tasks. But if we begin to seriously imagine a world where AI is the primary actor — where agents collaborate, make decisions, and carry out tasks — then these tr…  ( 9 min )
    Introduction to KEDA in Kubernetes: An Event-Driven AutoScaler
    KEDA is an open-source cloud native project under CNCF that enables Kubernetes to scale applications based on the events they consume. By leveraging event-based scaling, KEDA empowers Kubernetes to automatically adjust the number of running instances of a containerized service in response to external events, such as messages in a queue or an incoming request from an event stream. This dynamic scaling approach optimizes resource utilization and ensures that applications remain highly available and responsive. KEDA stands for Kubernetes Event-Driven Autoscaling. It is an extension of Kubernetes that enables autoscaling of workloads based on external events. Unlike traditional Kubernetes Horizontal Pod Autoscaler (HPA), which scales pods based on resource metrics such as CPU or memory usage, …  ( 6 min )

    Monorepo with Bun
    Hello Had this idea recently. I built this project management tool kinda like Jira, called kiffari, and now I’m working on turning it into something that runs locally, using markdown files as a database. It’s called kiffarino. The whole point is to keep tickets right next to the code that handles them But this post isn’t really about that. It’s about how much I’ve gotten used to bun as my go-to JavaScript runtime. I almost forgot it can also transpile TypeScript for Node, work as a package manager, and handle monorepos too. It does all of it. Over the past few months I’ve moved most of my stuff to bun. It just makes sense. I love JavaScript. It’s the language I use the most and the one I feel fastest with. TypeScript grew on me too.

    I attended the Build to Learn event to explore new ideas, gain knowledge, and enhance my skills. During the event, a Hackathon program was conducted, and we were given a topic for a mini project with a 3-hour time limit to complete it. Our team consisted of 4 members, and our assigned topic was to create a Water Reminder App with animations and interactive features to encourage people to drink more water. A fun and interactive water drinking reminder app where users care for a virtual fish pond. Every time you drink water, you tap the pond to add water and keep the fish alive. If you forget to drink (and tap the pond), the water level decreases and the fish become sad or sick — and eventually, they can "die" if ignored for too long.

    Fixing 'Dynamic Web Module cannot be uninstalled' Error in Spring Boot Maven Project (Eclipse)
    Introduction: Today, I encountered a frustrating but educational error while working on a Spring Boot project in Eclipse. The error message read: "One or more constraints have not been satisfied. Utility Module and Dynamic Web Module 6.0 cannot both be selected." If you're new to Spring Boot or Maven, this might confuse you — here’s what it means and how I resolved it. Spring Boot is designed to run as a standalone JAR with an embedded server (like Tomcat). It doesn't need or support legacy Java EE modules like the Dynamic Web Module. Eclipse, however, sometimes misinterprets your project structure and adds these facets automatically, causing conflicts like: Dynamic Web Module cannot be removed Utility Module conflicts with Web Module Spring Boot controllers not working Delete Eclipse’s Facet Metadata: .settings/, .project, and .classpath from the project folder Re-import Project: File → Import → Maven → Existing Maven Project Ensure Correct Maven Configuration: jar Run the Project with: mvn spring-boot:run OR Run As → Java Application on your main class Fix the Controller: java @Controller public class HomeController { @RequestMapping("/") @ResponseBody public String home() { System.out.println("Hit HomeController"); return "Welcome to Spring Boot!"; } } ### 🔎 Lesson Learned: * Don’t use `Dynamic Web Module` with Spring Boot * Use embedded server – not external WAR deployment unless required * Always check controller method return types and annotations * Spring Boot thrives on simplicity — don’t force Java EE structures into it ### 💬 Final Words: I faced this issue for hours and now fully understand why Spring Boot doesn't need the overhead of servlet container configuration. If you're facing the same — **delete Eclipse metadata, use pure Maven, and let Spring Boot do its magic.**  ( 3 min )
    Restarting My Java Journey: From Exam-Oriented Learning to Becoming a Real Developer
    Introduction Last year, I began my journey into Java programming. Like many students, I focused mainly on what was taught in the university syllabus—just enough to pass exams. I didn’t explore Java deeply, nor did I truly understand how to approach learning programming as a skill, rather than a subject. Now, I’ve decided to start over, not because I failed, but because I finally understand what I want—to become a professional Java developer who writes clean, working code and can build real-world applications confidently. When I first learned Java, my focus was limited to: Clearing university exams Memorizing definitions and syntax Completing assignments just to get grades I built a small project using Servlets, JSP, and Hibernate, but deep down, I felt unsure about how much I actually un…  ( 4 min )
    A Beginner’s Note on Natural Language Processing: Key Takeaways
    Ever wondered how AI tools like ChatGPT, Siri, or Grammarly understand what you are saying and respond like a human? That’s all thanks to Natural Language Processing (NLP), a branch of Artificial Intelligence (AI) that helps machines make sense of human language. NLP sits at the intersection of computer science, linguistics, and deep learning. It’s the reason why AI can translate languages, summarize articles, answer questions, and even chat with you (chatGPT 😆). As a subfield of Deep Learning, NLP uses neural networks to process and generate human language in a way that feels surprisingly intelligent. NLP is a subfield of Deep Learning, which itself is part of the broader world of Machine Learning. While traditional ML models rely on structured data (like numbers and tables), NLP deals w…  ( 5 min )

    You Don’t Need to Learn Everything — Learn This Instead 💯
    "There’s a new JavaScript framework every week." A 2024 survey of over 70,000 developers by Stack Overflow found that 60% of developers feel overwhelmed by how fast the tech industry evolves.

    Scale APP using Dependency Inversion Principle
    What is DIP? Dependency Inversion Principle is one of the SOLID Principle. It states that High Level Module shouldn't depend on low level modules, Both should depend on abstraction. Means, the code that handles business-logic shouldn't depend directly on the implementation details. Instead they both should depend on interfaces/abstract Class.

    I created a Facebook marketplace listing assistant.
    Hey folks, If you’re a car seller (or just someone who flips cars on the side), you know how annoying and repetitive it is to post each vehicle manually on Facebook Marketplace. I got tired of doing it myself, so I built a free tool: Facebook Marketplace Listing Assistant. What it does: Post multiple vehicles in just a few clicks — no more one-by-one hassle. Uses your current Facebook session — no sketchy logins or API setups. Built with dealers in mind, but works for anyone. Totally free — just something I built to save time. If this sounds useful, drop a comment and I’ll send you the GitHub link.  ( 3 min )

    Relationships in Power BI
    Power BI is a powerful tool for data analysis and visualization, but its real strength lies in how it connects different tables through relationships. These relationships allow you to combine data, filter across tables, and create interactive reports with ease. 📘 What Are Relationships 🧩 How Relationships Are Categorized Cardinality Cross-filter direction 1️⃣ Cardinality a. One to Many (1:*) b. Many to One (*:1) c. One to One (1:1) d. Many to Many (:) 2️⃣ Cross-filter Direction a. Single Direction As I conclude, I’d like to emphasize that defining relationships correctly in Power BI is critical to building a robust and accurate data model. By understanding cardinality and cross-filter direction, you can ensure your data behaves as expected across dashboards and reports. Take the time to plan your relationships carefully they are the backbone of meaningful, interactive insights in Power BI.  ( 4 min )

    How to Create Your Own Laravel String Helper Method Using a Macro
    Laravel's String helper offers many useful methods you can use in your application. We can also create our own laravel string helper method using a macro. For example, I want to create a randomSlug method that turns a string into a slug and appends a random string. use Illuminate\Support\Str; Str::macro('randomSlug', function ($slug, $length = 6) { return Str::slug($slug . ' ' . Str::random($length)); }); To use the method throughout your Laravel application, register the macro in the boot method of AppServiceProvider. <?php namespace App\Providers; use Illuminate\Support\ServiceProvider; use Illuminate\Support\Str; class AppServiceProvider extends ServiceProvider { public function register(): void {} public function boot(): void { Str::macro('randomSlug', function ($slug, $length = 6) { return Str::slug($slug . ' ' . Str::random($length)); }); } } Here's how to use the custom helper in a controller. <?php namespace App\Http\Controllers; use Illuminate\Support\Str; class TestController extends Controller { public function test() { return Str::randomSlug('Hello World'); } } The output will be like this: hello-world-tn8hfd Using macros, we can create custom methods on Laravel's string helper to make string manipulation easier in a Laravel application.  ( 3 min )

    Higher Order Functions in JavaScript – Map, Filter, Reduce Deep Dive
    JavaScript’s functional programming capabilities shine through its higher-order functions, which allow developers to write concise, reusable, and expressive code. Among these, map, filter, and reduce stand out as essential tools for transforming and manipulating arrays. Introduced with ES5 and enhanced in later standards, these methods leverage the power of callbacks to process data efficiently. This deep dive explores their mechanics, use cases, and best practices, helping you harness their full potential. Higher-order functions are functions that can take other functions as arguments or return them as results.

    Transitioning from Assembly to C: Challenges and Solutions for Programmers Effectively
    The history of programming is marked by significant milestones, one of which is the transition from assembly language to C. This shift revolutionized the way programmers wrote code, enabling them to create more portable, maintainable, and efficient software. However, this transition was not without its challenges. Programmers had to adapt to a new language, syntax, and programming paradigm, overcoming obstacles that arose from the differences between assembly language and C. The early days of programming were characterized by the use of assembly languages, which were symbolic representations of machine code. Assembly languages were closely tied to the hardware architecture, requiring programmers to manually manage registers, memory, and other hardware resources. This low-level programming …  ( 8 min )

    How do you approach polymorphism in your PHP projects?
    Polymorphism in PHP is an object-oriented programming concept that allows different classes to be treated through a common interface or parent class. It enables you to call the same method on different objects, each responding in its own way. This promotes code flexibility and scalability, making it easier to extend functionality without modifying existing code. A common example is having multiple classes like PdfExporter, CsvExporter, and XmlExporter all implementing an export() method from a shared interface — allowing you to work with any of them interchangeably in your code. Do you find it makes your codebase more maintainable — or more complex? Have you ever replaced polymorphism with simpler conditional logic for readability? In Laravel (or other PHP frameworks), where have you found polymorphism most useful? Do you think polymorphism is overused in some PHP projects, or is it underutilized compared to what it can offer?

Fitur ini memungkinkan kita membangun struktur data kompleks dengan atribut, metode, pewarisan, dan pengaturan khusus. kelas? kelas adalah sebuah blueprint atau catak biru untuk membuat objek (instance) yang memiliki data (atribut) dan perilaku (metode). kelas :Mobil: mewarisi Kelas baru dapat mewarisi properti dan metode kelas lain menggunakan kata kunci mewarisi. kelas :MobilSedan: mewarisi : Mobil: Jika :Mobil: memiliki metode atau atribut tertentu, maka :MobilSedan: akan mewarisinya secara otomatis. punggung Perintah punggung digunakan untuk menetapkan nilai awal instance berdasarkan variabel global: atur :warna: = "merah" atur :kecepatan: = 120 kelas :Mobil: punggung :warna:, :kecepatan: Penguatan: Perilaku Tambahan Bagian Penguatan digunakan untuk mengatur perilaku lanjutan pada metode atau atribut. Misalnya: kelas :Pengguna: Penguatan masuk() tumpuk "verifikasi" melontarkan "akses ditolak" MenangkapBasa: #debug Penjelasan kode: tumpuk: Menyisipkan logika tambahan. melomtarkan: Mengatur respon jika gagal. MenangkapBasa: #debug: Menyalakan debug atau log saat metode dijalankan. metode: Mendefinisikan Fungsi di Kelas Metode adalah fungsi yang dimiliki kelas. Di Earl, kamu bisa menuliskannya seperti ini: kelas :Orang: meotode sapa() tampilkan "Halo!" Saat instance memanggil metode sapa, ia akan menjalankan perintah yang diberikan. atur :merk: = "Toyota" atur :cc: = 1500 kelas :Mobil: punggung :merk:, :cc: metode info() tampilkan :merk: :cc: Fitur kelas dalam bahasa Earl memberikan pondasi penting untuk pemrograman berorientasi objek.

    Error Budget Is All You Need - Part 2
    In part 1 I proposed a simple modification to Google’s Multi-Window Multi-Burn Rate alerting setup and I showed how this modification addresses the cases of varying-traffic services and typical latency SLOs. While my proposed solution was simply to alert on the error budget instead of the error rate, in this part I will show how we can still alert on the error rate but do it correctly. More importantly, the novel error-rate-based alert I will develop will expose a dynamic time-dependent burn rate expression which in contrast to Google’s static one leads to built-in compatibility to varying-traffic services. A certain disadvantage in my proposed solution in part 1 is that the metric which it alert on is the error budget while the metrics we care for when implementing SRE are the SLIs (or th…  ( 8 min )

    Boost Your React App Performance with Lazy Loading
    🧠 What Is Lazy Loading? 💡 Key Benefits 🛠️ How to Implement Lazy Loading in React import React, { lazy, Suspense } from 'react'; const LazyComponent = lazy(() => import('./LazyComponent')); function App() { return ( ); } 2.Route-Based Loading (React Router) import { BrowserRouter as Router, Routes, Route } from 'react-router-dom'; import { lazy, Suspense } from 'react'; const Home = lazy(() => import('./Home')); const ImagePage = lazy(() => import('./Image')); function App() { return ( } /> } /> ); } 3.Image & Component Libraries import LazyLoad from 'react-lazyload'; 4.Dynamic Imports with Buttons or Interactions const LazyProfile = lazy(() => import('./LazyProfile')); function App() { const [showProfile, setShowProfile] = useState(false); return ( setShowProfile(!showProfile)}> {showProfile ? 'Hide' : 'Show'} Profile {showProfile && ( )} ); } ✅ Best Practices Lazy-load only non-critical code - e.g., modals, routes, images. Always pair with fallback UI using Suspense. Consider preloading components likely to be used soon. Handle errors gracefully with Error Boundaries. Test on real devices and low-bandwidth connections. 🔚 Final Words Done right, lazy loading reduces initial payloads, improves perceived responsiveness, and keeps your app scalable. Done poorly, it adds complexity and brittle flows. Try adding a lazy-loaded route or image to your next React build - it could save your user seconds of load time.  ( 3 min )

    How to use Glowscript; The ultimate guide
    https://github.com/CampbellSoftware/Tardigrade Hello. I am Grayson. I recently built a programming language I call Glowscript. It doesn't have a compiler yet, but runs in a tkinter script. Here is how you can use Glowscript for sorting and messing with data! PRINT Hello World Let's break it down. The PRINT function prints Hello World onto the terminal. Pretty straightforward! SET x Hello SET y World PRINT x y Let's break it down. SET sets two variables named x and y with values "Hello" and "World". Then, PRINT prints them out. SET x 0 PLUS x 1 PRINT x LOOP 2 5 Let's break it down. SET sets x to 0, and plus adds 1 to x. PRINT prints x to the console. The LOOP function goes to line 2 5 times. In other words, every time you hit LOOP, it's counter, 5, goes down by 1, and once the counter reaches 0, LOOP does nothing.

It was mostly about placing images and making the surrounding design elements align visually. But here’s the thing: I started laying things out without a clear, defined goal or a vivid end image in mind. I just had a general feeling, maybe something like this and went from there. Design Fatigue, or Just a Weak Idea? After spending so long on the same page, I started losing perspective. Is this layout actually good? Or am I just getting used to it? I finished a version of the section, but I couldn’t shake the feeling that it’s… just okay. Not bad, but not memorable either. And that’s a problem. If It Doesn’t Move Me, It Won’t Move the User One thing I’ve been thinking about is this: If the creator doesn’t feel anything while making it, how can we expect the viewer to feel something or take action? That’s the scary part about visual design. It's not enough for it to function; it has to connect. Tomorrow's Focus: Figure Out Why Instead of tweaking the layout endlessly, I’ll take a step back tomorrow. I want to understand why this layout doesn’t feel right: Is it the lack of contrast? Are the images too weak or generic? Is the hierarchy unclear? Am I trying to say too much with too little? I’ll try to write down a few specific reasons, no matter how small, and build from there. Design isn’t just about moving elements around. It’s about making decisions with emotion and clarity. Today I moved pieces. Tomorrow I’ll try to move meaning.

    Python Fundamentals: asgi
    ASGI: Beyond the Web – A Production Deep Dive Introduction Last year, a seemingly innocuous deployment of a new microservice responsible for real-time feature flagging triggered a cascading failure across our core platform. The root cause wasn’t a code bug in the feature flag logic itself, but a subtle deadlock within the ASGI server handling the persistent WebSocket connections. The server, under sustained load, was exhausting its event loop resources, leading to unresponsive services and ultimately, a partial outage. This incident highlighted a critical gap in our understanding of ASGI’s intricacies and the importance of careful resource management in async Python applications. This post aims to share lessons learned from that incident and provide a comprehensive, productio…  ( 7 min )
    "From Excitement to Disappointment – My Yesterday’s Story"<<<😃 😞
    Yesterday, I was really excited since joining the course, wondering when we would attend a hackathon — because my brother had told me that if a hackathon happens, don't miss it, attend it, you'll get good experience and learn something new. Then yesterday, I got a chance to attend hackathon. So, I woke up early in the morning and got ready to go. But suddenly, I got food poisoning, so I couldn't attend. I felt really bad. Some of my friends attended and later shared their experiences, which made me feel even worse. The day before, I had eaten chicken fried rice at a hotel in Chennai, and it didn’t suit me. My parents scolded me and told me that hereafter, I shouldn’t eat non-veg in Chennai. I spent half of the day feeling upset, then I slept well in the afternoon. In the evening, I went to the temple, then visited my grandmother’s house, had dinner there, and slept... That’s how my day went...  ( 3 min )

    [pt-br] 🧪Como criar seu lab Linux com Vagrant
    Oi, gente! 👋 Quero compartilhar uma ferramenta que conheci recentemente e tem me ajudado demais a criar laboratórios para estudar Linux: o Vagrant. Basicamente, o Vagrant automatiza a criação e o gerenciamento de máquinas virtuais. Mas atenção: ele não cria a VM sozinho — ele precisa de um provedor para isso (tipo VirtualBox, VMware, Hyper-V, Docker...). Para este exemplo, vou usar o VirtualBox, e todos os comandos foram feitos pelo PowerShell, no Windows mesmo. Primeiro, baixe e instale essas duas coisas: VirtualBox Vagrant Depois que instalar tudo, abra o PowerShell (pode usar o atalho Win + S, digitar "powershell" e abrir como administrador). Escolha onde você quer criar sua máquina. No meu caso, usei meu segundo disco (D:), então entrei na pasta com: cd D:\labs Aqui dá para seguir do…  ( 3 min )
    NodeJS Fundamentals: dgram
    Diving Deep into Node.js dgram: Production UDP for the Pragmatic Engineer Introduction We recently encountered a challenging scaling issue with our internal event notification system. Built as a REST API, it was struggling to handle the sheer volume of low-latency, one-way notifications required by our microservices architecture. Each service needed to broadcast events (e.g., “order created”, “user updated”) to interested subscribers without requiring a response. Polling was unacceptable due to latency and resource consumption. WebSockets were overkill for this simple broadcast pattern. This led us to revisit UDP and Node.js’s dgram module. This isn’t a “first look at UDP” post; it’s about how to leverage dgram in production Node.js systems where reliability, scalability, a…  ( 7 min )

    🧪How to Build a Linux Lab Using Vagrant
    Hello, folks! 👋 Vagrant. At its core, Vagrant automates the creation and management of virtual machines. But here's a crucial point: it doesn't create the VM on its own. It needs a provider to do that (like VirtualBox, VMware, Hyper-V, Docker, etc.). For this example, I'll be using VirtualBox, and all commands were executed in PowerShell on Windows. First things first, download and install these two: VirtualBox Vagrant Once everything's installed, open PowerShell. You can use the Win + S shortcut, type "powershell," and run it as an administrator. Choose where you want to create your virtual machine. In my case, I'm using my second drive (D:), so I navigated to the folder with: cd D:\labs You have two paths here. If you want to get straight to it, you can use: vagrant init centos/7 This…  ( 4 min )

    NodeJS Fundamentals: static method
    Static Methods in JavaScript: Beyond the Basics Introduction Imagine you’re building a complex data visualization library for a financial trading platform. Users need to perform a variety of statistical calculations on time-series data – moving averages, standard deviations, correlation coefficients. Each calculation requires a specific algorithm, but doesn’t inherently belong to any particular instance of a TimeSeries object.

    EXSQL: An open-source SQL language extension for customizable querying
    I have started to create a new open source project called EXSQL, which is a direct improvement to SQL, adding more modern enhancements and better syntax for complex applications. Enhanced and eXtended Structured Query Language is actually a transpiler (like JSX), which seeks to improve SQL by simplifying tasks and improving the syntax, such as inheritance in databases, making it a rather complicated and exhausting task, instead, thanks to EXSQL we could do something like “SUBTYPE OF” in a CREATE TABLE and it would generate all the necessary logic for the database but we would be using EXSQL to do everything. Right now I just did something simple (and not working) with python and Lark and created the repository where the project will be saved. I'm currently looking for feedback and help to carry out the project. Github Repository: https://github.com/Greem3/EXSQL  ( 3 min )

    Ubuntu Fundamentals: GRUB
    GRUB: Beyond the Boot Menu - A Production Deep Dive Introduction A recent production incident involving a failed kernel update on a fleet of Ubuntu 22.04 LTS servers highlighted a critical dependency often overlooked: GRUB. The update, while successful in applying the new kernel, left the servers unbootable due to a misconfigured GRUB entry. This resulted in a 3-hour outage requiring emergency console access and manual GRUB repair on each machine. This isn’t an isolated case. In cloud environments, where immutable infrastructure is favored, and on-premise servers are often managed remotely, a broken GRUB configuration can translate to significant downtime and recovery costs. Mastering GRUB isn’t just about understanding the boot process; it’s about ensuring system resilience, …  ( 7 min )

    NodeJS Fundamentals: side effect
    Understanding and Leveraging Side Effects in Production JavaScript Introduction Imagine a large e-commerce platform where product recommendations are dynamically updated based on user browsing history. A naive implementation might directly manipulate the DOM within a recommendation component whenever a user views a product. This seemingly simple approach quickly spirals into a nightmare of unpredictable rendering, difficult debugging, and performance bottlenecks. The core issue isn’t the recommendation logic itself, but the side effects introduced by directly interacting with the browser’s environment.

    Drupal + Gutenberg: Not a Match Made in Heaven, But Full of Potential
    When Gutenberg was introduced to WordPress in 2018, it fundamentally redefined how content is created and structured. Instead of working within a large, monolithic WYSIWYG field, Gutenberg brought a block-based editing experience allowing users to compose rich content layouts using reusable and configurable blocks. This shift empowered editors and site builders alike, introducing modularity without requiring full developer involvement for every content change. The block-based philosophy behind Gutenberg aligns closely with the field-based system of WordPress. Each content type in WordPress comes with a pre-defined set of fields, but Gutenberg blurred those lines by making layout and content structure part of the same visual experience. Blocks could be text, images, galleries, buttons even …  ( 5 min )
    How AI Killed My Coding Brain
    There was a time when I could stare at a blank terminal, summon a coffee-fueled epiphany, and build things from scratch. Today, I stare at my editor—and ChatGPT stares back. AI didn’t just assist my workflow—it took over it. What started as a helpful little sidekick for debugging soon became the architect, planner, and even the copywriter for my commits. Want to center a div? “Hey ChatGPT, give me a Tailwind class to center this.” Need to write a CRUD API? “Write me an Express.js API with MongoDB and JWT auth.” Stuck on a bug? “Here’s the error log, now fix it.” And it works. Every time. Which is great… until you realize your brain hasn't written a loop by hand in weeks. There’s something oddly dystopian about knowing how to write something but choosing not to.

This isn’t an isolated event. Modern Ubuntu-based infrastructure – whether cloud VMs, on-prem servers, or containerized environments running long-term support (LTS) releases – relies heavily on a stable and performant kernel. Ignoring kernel-level details is no longer a viable option for maintaining reliable, scalable, and secure systems. This post dives deep into the Ubuntu kernel, focusing on practic…  ( 6 min )
    When the Code Ends but the Screen Doesn't: The Hidden Cost of a Connected Life😮‍💨
    We live in the era of hyperconnectivity. As a developer, I spend at least 8 hours a day in front of a computer. At 39, having recently transitioned from an executive role to the tech field, I understand this is part of my job. The problem isn’t screen time at work — it’s what happens afterward. In my free time, instead of disconnecting, I dive into mobile games, scroll Instagram almost on autopilot, and binge-watch YouTube videos. I have an 8-year-old son, and every time I see him imitating my habits, I feel a deep discomfort. Because in the end, it's not what we say — it's what we do that shapes who they become.

    The concept of memory is very important in Javascript and today we will deep dive into this. At the end this concept of memory allocation will be helpful to understand another important concept of serialization and deserialization. Primitive values are immutable and have a fixed size, so they can be easily stored and accessed in the stack. Objects are mutable and have a variable size, so they need to be stored and accessed in the heap, which is more flexible but also slower. let fname = "John"; // string literal, stored in stack memory let lname = "Doe"; // string literal, stored in stack memory let newfname = fname console.log(`First Name: ${fname}, Last Name: ${lname}`); // Accessing string literals from stack memory console.log(`New First Name: ${newfname}`); // Accessing new variable…  ( 7 min )

    Why Composition over Inheritance Is More Than Just a Design Principle
    In many codebases, inheritance is still the default tool for reusing behavior. But in real-world, evolving systems, inheritance often brings more rigidity than flexibility. Composition offers a significantly more adaptable and maintainable alternative. Inheritance implies an “is-a” relationship between objects. While this seems clean in theory, it quickly leads to practical problems: Rigid hierarchies: Behavior is locked into base classes and difficult to adjust without side effects. Tight coupling: Subclasses depend heavily on base classes. A small change in the base can ripple through the system. Low reusability: Behavior is tied to a particular class hierarchy and hard to extract or share. Poor maintainability: Deep inheritance trees obscure behavior and make debugging harder. With comp…  ( 4 min )

    Why I Built My Own File Conversion API (And You Probably Shouldn't)
    The Problem That Started It All ConvertAPI: $30/month for 1,000 conversions Wait, what? Node.js + Express Conversions Supported: Markdown ↔ HTML The entire backend is maybe 6-700 lines of actual conversion logic, and tons of plugins I configured. The rest is authentication, rate limiting, billing integration, and error handling. My pricing: 100 free conversions/month That's roughly $0.0012 per conversion vs the industry's $0.03. Sometimes when you say to yourself " I could do this better" You are right. A lot about securing a service, this is my first SaaS project, but hardly my first JS one. Sometimes things cost way more than they need to, this is running on a small vps, but if people use it I will upgrade to keep performance great. The overhead is pretty minimal. Time sink: This was supposed to be a weekend project. It's been weeks. Support burden: Users expect enterprise reliability at indie prices Market risk: Competitors could drop prices tomorrow Opportunity cost: Could have built something more innovative But sometimes it's worth it if: The pricing gap is truly absurd (25x counts) The Results So Far Live for a day. Users signing up.Product Hunt pending. More importantly: I learned that sometimes the "impossible" competitive landscape just needs someone willing to charge reasonable prices.

    Exploring @HostListener in Angular — Decorator series -2 🔍
    Hey developers! 👋 Welcome back to our series on Angular decorators. In this post, we're diving into one of the lesser-discussed but incredibly powerful decorators in Angular: @HostListener. We’ll explore how to use it, how it gets compiled under the hood, and a few interesting use cases you may not have tried before. @HostListener? The @HostListener decorator allows you to listen to DOM events on the host element of a directive or component and run custom logic in response. It’s a clean way to bind events without touching the template. @HostListener(eventName: string, [args: string[]]) Let’s start with a basic example where we listen to native DOM events like mouseover and mouseleave to dynamically apply styles. We’ll create a directive that zooms in text when hovered. import { Directi…  ( 5 min )

    From Distraction to Direction: My Journey Post-Bachelor's
    After completing my bachelor's degree, I found myself completely lost. I had no internships, no job offers, and no real skills I could confidently showcase on my resume. But surprisingly, what frustrated me the most wasn’t the lack of opportunities—it was the lack of clarity. I had no idea what I truly wanted to do with my career or life. In that frustration, I began desperately searching for shortcuts—hoping someone would just tell me, “This is a good skill, learn it, it works for everyone.” I spoke to seniors, listened to all kinds of advice: “Learn this, learn that.” But all the mixed guidance only added to my confusion, leading to mental burnout. The truth is—when you don’t have clear goals of your own, it’s easy to adopt someone else’s dreams as if they were yours. You start chasing w…  ( 4 min )

    How to Prevent Enter from Submitting a Form Input With Javascript
    By default, when the Enter key is pressed in a form's input field, it will trigger the form to be submitted. This behaviour can be prevented with JavaScript — here's how: Listen for key presses in the input using the keydown event. Check the key pressed by reading the key property of the event object. If the key is Enter, prevent the default behaviour (triggering form submit) by calling preventDefault method on the event object. For example: document.querySelector('input') .addEventListener('keydown', (e) => { if (e.key === 'Enter') { e.preventDefault(); } }); This way, every time Enter is pressed in the form's input field, the form won't be submitted.  ( 3 min )

    Maintenance releases 0.5X.0 of the GitHub Action for Checking Spelling
    I have recently done two maintenance releases of the GitHub action for checking spelling. 0.50.0 on 2025-05-16 0.51.0 on 2025-05-20 I did one as the base image was updated and could might aswell ship it, since not much else was planned. From the change log for 0.50.0: Docker image updated to Python 3.13.4 slim via PR #246 from Dependabot. Release notes for Python 3.13.4 A few days after a PR for updating the base image again came in. From the change log for 0.51.0: Docker image updated to Python 3.13.5 slim via PR #249 from Dependabot. Release notes for Python 3.13.5 Release 0.49.0 was made on 2025-05-22 and prior to that 0.48.0 on 2025-04-01, so I was satisfied with the monthly cadence of releases. But the world around us changes constantly, so I thought I might as well keep up and get the chore done. For myself this results in a bunch of PRs to review and merge, next week when Dependabot notifies me of the 0.51.0, but I can live with that and I can handle it on my commute to work on the phone.

    Day-40 Understanding Props Drilling in React (With Examples)
    When you're learning React, one concept you’ll often come across is props drilling. At first, it might seem confusing—but once you understand what’s happening, it’s quite straightforward. Let’s break it down. Props Drilling is when you pass data from a parent component down to deeply nested child components using props—even if the intermediate components don’t actually need that data. This often leads to bloated and harder-to-maintain code, especially in large apps. Imagine you have this component structure: App → Parent → Child → GrandChild Now, let's say App has some data that GrandChild needs. Here’s what props drilling would look like: function App() { const user = "Tamilselvan"; return ; } function Parent({ user }) { return ; } function Child({ user }) { return ; } function GrandChild({ user }) { return Hello, {user}! ; } Notice how Parent and Child don’t use the user prop, but they still have to pass it along just so GrandChild can use it. That’s props drilling. Hard to maintain – Changing the data structure means updating multiple components. Cluttered code – Components get unnecessary props. Performance issues – Every component in the chain re-renders when the prop changes. React Context API Share data across components without manually passing props. const UserContext = React.createContext(); function App() { return ( ); } function GrandChild() { const user = useContext(UserContext); return Hello, {user}! ; } State management tools Like Redux, Zustand, or Recoil for large-scale apps. Props drilling isn’t always bad—it’s just a sign that your app might need a better way to manage shared state. For small apps, it’s totally fine. But as your component tree grows, learning tools like Context API becomes essential.  ( 4 min )

    Building CODA: My AI Coding Assistant (As a Teen Dev)
    Hi there! I’m Kaden, a 16-year-old developer building an AI assistant called CODA: A Creative Optimization & Development Assistant. CODA is designed to create, edit, and optimize code by analyzing your entire project—because it actually has local access to your files. This means it can give advice that makes sense in the full context of your work, not just a single file or snippet. I started building CODA a couple of weeks ago, and I’ll be honest—I'm not some genius. I used ChatGPT a lot to help write the code. But soon, I hope to rely on CODA alone. Right now, I'm in Phase 2, where CODA can read all files in your project, understand and generate code based on the full context, and offer targeted coding advice. My plan for the future is to make a smart debugger, an improved memory system (because I'm currently using .json files), Text-to-speech, speech-to-text, and even a wake word so it starts feeling more like JARVIS. If you'd like to stick around, I’ll be posting another update when Phase 2 is complete, and outlining the roadmap for Phase 3. Thanks for reading!

Creating a new page is as simple as creating a new +page.svelte file in your routes directory. Loading data for that page is done in a sibling +page.server.js file. It's intuitive, co-located, and makes the entire structure of the app easy to reason about. I'm not abandoning React tomorrow, but my skepticism is gone. SvelteKit offers a fantastic developer experience and incredible performance. If you're a React dev on the fence, I highly recommend giving it a try. What are your thoughts on SvelteKit?  ( 4 min )

    JavaScript delete operator might cause some unexpected performance issues.
    So I was working on some benchmarking with a piece of code in JavaScript and I was scratching my head over the runtimes that I was seeing. I literally could not make sense of what was happening. And in a wild attempt at debugging, I stumbled upon a quirk that I had never known. The v8 engine does not really like the delete operator. And using this operator on an object can have a tangible impact on the performance of your code. In my case, it was almost 3 times worse performance than if I had manually set that key to undefined or false That said, I was able to reproduce this in Safari v18.5 as well along with all Chromium based browsers. So not really sure if this behavior is limited to the v8 engine. Here’s a simple code I wrote based on my experience to easily benchmark the performance i…  ( 4 min )
    Beyond switch-case: Type-safe Pattern Matching in TypeScript
    🐙 GitHub Pattern matching in TypeScript has become an essential part of my daily workflow, both in React and Node.js. Personally, I haven't found a need for switch-case statements—I can't even recall the last time I used one. In this post, I'll share practical pattern matching techniques that I rely on regularly. All the reusable code can be found in the GitHub repository. Often, when we reach for a switch-case statement, our real goal is to run different logic depending on the value of a union type or enum. For example, in a music theory app, we need to generate different note patterns for different scale types. Each scale type—like blues, full, or pentatonic—has its own function that implements the specific logic for that scale, but all of these functions share the same input and output…  ( 11 min )

    What is pure function?
    Understanding Functional Programming Functional programming is a programming style or paradigm that focuses on building software by creating and combining functions. Think of it like this: you write small, self-contained pieces of code (functions) that take an input, perform some operations, and then produce an output. A core idea is that for the same input, you will always get the same output, making the code predictable. Reusable: Functions are designed to be independent, meaning you can easily reuse them across different parts of your code or in various modules, as long as you need their specific output. Stateless: Functional programs aim to be "stateless." This means a function's output depends solely on its inputs, not on any changeable internal or external state. No matter how man…  ( 6 min )

    Why You Need to Humanize Your AI Written Content
    Your AI content sounds like a robot wrote it. Readers can tell within seconds, and they're clicking away faster than you can say "optimize for engagement".

    Mastering Design Patterns: The foundation
    Ever looked at your code and thought, “There must be a better way to organize this.” That’s where design patterns come in. In this post, we will explore what design patterns are, why they matter, and how they are categorized. Design patterns are proven, reusable solutions to common software design problems. Think of them like templates or blueprints—not code that you copy and paste, but rather ideas and structures that guide you in solving recurring problems in a clean, efficient, and maintainable way. Design patterns generally fall into three broad categories, each addressing a different kind of software design problem: 1. Creational Patterns object creation mechanisms, trying to create objects in a manner that is suitable to the situation. They help make a system independent of how its objects are created, composed, and represented. Examples: Singleton, Factory Method, Builder, Abstract Factory, Prototype 2. Structural Patterns composed to form larger structures. They help ensure that if one part of a system changes, the entire system doesn't need to do the same. Examples: Adapter, Composite, Proxy, Decorator, Bridge, Facade 3. Behavioral Patterns communication between objects, focusing on the responsibilities and the flow of control in a program. Examples: Observer, Strategy, Command, State, Iterator, Mediator In the upcoming posts, I’ll break down each design pattern—complete with real-world analogies, use cases, pros & cons, and practical examples in code. Whether you’re a beginner developer or someone brushing up on architectural skills, this series will help you think more clearly about software design. Have you used any design patterns in your projects? Or do they still feel abstract and academic? Drop a comment below—I’d love to hear your thoughts or questions!  ( 3 min )

    Snapshot Strategies: Optimizing Event Replays
    "Replaying 10,000 events just to check a balance? There’s a better way." Event sourcing gives you time-travel superpowers—until you realize: Rebuilding an aggregate from 1M events takes minutes. Your read API times out waiting for a replay. Testing becomes painfully slow. Snapshots fix this by periodically caching state, so you only replay recent events. Here’s how to implement them without breaking event-sourcing principles. 1. When Do You Need Snapshots? Problem Signs Slow reads: GET /users/123 triggers a 5-second replay.

    Entendendo Back Pressure: O Semáforo dos Seus Sistemas Distribuídos
    Seu sistema está lento, travando sob carga ou apresentando falhas em cascata? Um dos culpados pode ser a ausência de um mecanismo crucial: Back Pressure. Em sistemas distribuídos, componentes se comunicam constantemente. Um producer (upstream) envia dados para um consumer (downstream) processar. Mas o que acontece quando o producer é muito mais rápido que o consumer? O consumer fica sobrecarregado, sua fila de processamento explode, a memória estoura e o sistema inteiro pode cair. É aqui que entra o Back Pressure. Back Pressure é um mecanismo de feedback que permite ao componente consumer (sobrecarregado) sinalizar ao producer (rápido demais) para que ele diminua o ritmo ou pare de enviar dados temporariamente. Pense nisso como um controle de tráfego. Em vez de deixar os dados fluírem sem …  ( 5 min )

    A Duet of Performance and Safety(1750444667598500)
    A Duet of Performance and Safety: Technical Analysis of Modern Web Frameworks As a third-year computer science student immersed in the world of computer science, my days are consumed by the logic of code and the allure of algorithms. However, while the ocean of theory is vast, it's the crashing waves of practice that truly test the truth. After participating in several campus projects and contributing to some open-source communities, I've increasingly felt that choosing the right development framework is crucial for a project's success, development efficiency, and ultimately, the user experience. Recently, a web backend framework built on the Rust language, with its earth-shattering performance and unique design philosophy, completely overturned my understanding of "efficient" and "moder…  ( 6 min )
    Automating Cron Job Setup with Ansible Like a Pro
    Hi there! I'm Maneshwar. Right now, I’m building LiveAPI, a first-of-its-kind tool that helps you automatically index API endpoints across all your repositories. LiveAPI makes it easier to discover, understand, and interact with APIs in large infrastructures. Keeping servers clean, logs trimmed, and disk space healthy? Cron jobs do the grunt work — but managing them manually? Pain. That’s where Ansible saves the day. Here's how I automated system maintenance jobs with a reusable Ansible role called cron-master. ansible-galaxy init roles/cron-master --offline ansible/ ├─ README.md ├─ ansible.cfg ├─ cron-master.yml # playbook to run cron-master role ├─ hosts.ini # inventory file ├─ install_ansible.sh # bootstrap script ├─ requirements.yml ├─ role…  ( 5 min )

    Implementing Log File Rotation in Go: Insights from logrus, zap, and slog
    In existing logging libraries, including Go’s built-in log/slog logging library, they typically support log file rotation and splitting. However, these features are not built in directly—they need to be actively configured by us to enable them. This article will explore several popular logging libraries, such as logrus, zap, and the official slog. We will analyze the key design elements of these libraries and discuss how they support the configuration of log rotation and splitting. When comparing the design of logrus, zap, and slog, one prominent commonality is that they all include the crucial property of io.Writer. This property plays a central role in the design of logging frameworks, as it determines the target location for log output. logrus is a feature-rich logging library for Go, p…  ( 7 min )
    Bad Interview, Good Practice
    LeetCode, Codewars, and similar sites that "test your skill" as a developer aren't good interview tools, but they can be good personal skill builders. Rather than highlighting developers who can follow direction and solve problems, using sites like these as skill-validation tools can strongly favor developers who memorized the answer rather than developers who can demonstrate skill in reading requirements, following instructions, and solving problems. Don't get me wrong; knowing the answer is an important part of development. Not reinventing the wheel saves us time, complexity, and risk. But there are different aspects of the role of developer, and knowing about a linked list is different than demonstrating the ability to recreate one while racing a clock. As a personal development tool, s…  ( 4 min )
    World Sea Turtle Day
    This is a submission for Frontend Challenge - June Celebrations, CSS Art: June Celebrations. World Sea Turtle Day (June 16) celebrates these ancient mariners who have navigated Earth's oceans for over 100 million years. Sea turtles are incredible creatures that face numerous threats, from plastic pollution to climate change. This CSS art honors their graceful swimming patterns and the underwater world they call home. Journey This piece challenged me to recreate the elegant motion of sea turtles gliding through water. I used CSS animations to simulate their distinctive swimming pattern - the way they gracefully move their flippers in a synchronized rhythm. The turtle shapes are created entirely with CSS, using clever combinations of border-radius, transforms, and pseudo-elements. The underwater environment features floating seaweed created with CSS animations and a gradient background that mimics the way sunlight filters through ocean water. I experimented with different animation delays to make each turtle move independently, creating a more natural scene. What I'm most proud of is the organic feel of the animations - they don't feel robotic or mechanical. The turtles seem to truly "swim" through their digital ocean. In future iterations, I'd love to add bubbles, more diverse marine life, and perhaps simulate the turtle's journey from nest to ocean.  ( 3 min )

    Azure Fundamentals: Microsoft.DataBoxEdge
    Bringing the Cloud to the Edge: A Deep Dive into Microsoft Data Box Edge Imagine you're a wind farm operator, generating massive amounts of data from hundreds of turbines. Sending all that data to a central Azure data center for processing introduces latency, bandwidth costs, and potential connectivity issues. Or consider a manufacturing plant with real-time quality control systems – a delay in analyzing sensor data could mean a defective product line. These scenarios, and countless others, highlight the growing need for edge computing. Today, 85% of new enterprise workloads are being built for the edge, and by 2025, an estimated 75% of all data will be generated and processed outside of traditional cloud data centers (Gartner, 2023).

    We're making our availability metrics public
    At Tigris Data, we provide object storage to our users. People put bytes into our servers with a name, and expect that come hell and high water, when they put in the name, they get the exact same bytes back. This is a very high trust position to be in because when people ask themselves things like “Oh, what would happen if my object storage provider is unreliable”, that conversation usually involves phrases like “Maybe we should have gone with The Big Cloud afterall”. Such conversations are rarely good for the business. If you store your data in Tigris, you shouldn’t need to worry about a status page full of green checkmarks or anything else that needs to be updated manually. As a result, we’re trying something different. We’re making our internal reliability and performance metrics publi…  ( 5 min )

    Meeting to Google Docs
    This is a submission for the Runner H "AI Agent Prompting" Challenge I built a super simple but surprisingly useful Runner H agent called “Meeting to Google Docs”. The goal? Just type in the details of your meeting, and boom — Runner H creates a clean, ready-to-use Google Doc titled with the meeting name and structured with your agenda. This agent is for anyone (like me!) who constantly has to jot down meeting notes, agendas, or brainstorms and just wants to skip the repetitive formatting and file creation. It takes 10 seconds instead of 10 minutes. runner.hcompany.ai How I Used Runner H Here’s how I set it up: Runner H instantly created a well-formatted Google Doc in my Drive — no extra clicks, no templates, no chaos. You can easily replicate this by typing your own meeting title and points — that’s it! No code, no learning curve. If you’ve ever scrambled 2 minutes before a call to create a doc, or juggled messy notes across apps, this is your fix. It’s great for: It doesn’t try to do everything — just one thing really well. And that’s the magic. ✨ I’ll be sharing this on Twitter and LinkedIn soon — will update with links here once it’s live!  ( 3 min )

    Lessons from 6 Months of Building AI Agents
    Over the past six months, I’ve been deep in the trenches working with AI agents. I’ve built prototypes, tested frameworks, broken things, and occasionally gotten something to work the way I intended. It’s been exciting — but also humbling. There’s a lot of hype out there, and while much of it is grounded in genuine progress, I’ve seen first-hand how different the day-to-day reality is from the glossy demos and blog posts. If you’re getting started with AI agents or just curious about what it’s really like, here are eight honest takeaways from my experience. 1. Most “AI Agents” Aren’t Really Agents You’ve probably seen demos of AI agents that can schedule appointments, handle customer support, or generate content for your brand. They look polished. They seem smart. But here’s the truth: Mos…  ( 6 min )

    My React Learning - Day [XI] (Component Drill, useEffect, CSS, JSON Handling)
    Hello Coders!! Today I learned some very useful and important concepts in React which are helpful to build real projects easily. Let me share them in simple words. 1.Component Drilling In React, when I want to pass data from Parent to Child components, we use props. Component Drilling. Example: function Parent() { const msg = "Hello from Parent"; return ; } function Child({ message }) { return ; } function GrandChild({ message }) { return {message} ; } Data passed from Parent → Child → Grandchild. 2.useEffect Hook I also learned about useEffect.

    Accelerate Development with Fast Feedback Loops Using MCP Browser and LLMs
    The world of modern web development is evolving. Now we're not talking about the notorious race of everyday emerging front-end frameworks or about the environments that have walked the path from text editors to powerful plugin-rich and adjustable IDEs for any purpose. LLMs are gaining power and becoming better and better so there are two ways to deal with it - deny it or accept it. In order to keep up with the more and more increasing speed of development it's always nice to revisit the current state of events and check new cool kids on the block. Nowadays the development process has become more like a copy-paste from the error trace to GPT and back. The tools are powerful, but we still require the middleman to handle all of them, to give the context. Context is still something we're tryin…  ( 5 min )

    Learning Web3 from the Ground Up: Smart Contracts and the Compact Language
    As I continue my journey through the world of Web3, I’ve been digging into the building blocks that make privacy-first platforms like Midnight possible (you can catch up on previous posts in the Midnight Dev Diaries!). This week, I focused on two foundational pieces that go hand in hand: smart contracts on Midnight and the Compact language that powers them. Smart contracts aren’t new to blockchain, but Midnight’s approach is unique. Instead of executing code directly on-chain, Midnight uses smart contracts to define rules that are enforced off-chain through zero-knowledge proofs. At the center of this system is Compact—a purpose-built language designed to make writing these privacy-preserving contracts both secure and practical. To better understand how this works in practice, I also worke…  ( 7 min )

    Borderlands 4 pre-orders open at $70, avoiding feared $80 price tag
    TL;DR: Borderlands 4 has dodged the dreaded $80 launch price, with its standard edition up for pre-order at $69.99 ($60/€70) ahead of its Sept. 12 release. Deluxe and Super Deluxe bundles will set you back $100 and $130, respectively, packing in post-launch DLC, skins and extra Vault Hunters. A bit of drama preceded the reveal: CEO Randy Pitchford’s flippant “If you’re a real fan, you’ll find a way to make it happen” comment on X sparked outrage, especially after he noted production costs had doubled since Borderlands 3. He’s since celebrated the $70 price on social media—some suspect it was a cheeky PR play to juice pre-orders—while other big publishers (cough Microsoft) are already eyeing $80 tags on upcoming titles.  ( 3 min )

    The Zen of Python Principles That Inspire Me as I Learn Python Programming for Cybersecurity
    • Introduction Mr. Uba Joseph Ugochukwu and his team in the “From Zero to Hero” python class, was my first time of hearing “The Zen of Python”. I had to do my research before I understood what it means. In a nutshell, it’s a list of 19 short rules that help Python programmers write better codes. These rules were written by Tim Peters, and they are easy to understand but full of wisdom. Here are 4 of those rules that really speak to me, and why I think they are important in my journey: Simple is Better Than Complex. Readability Counts. Errors Should Never Pass Silently. “wow, so I’m going to be a good fit in cybersecurity after learning python”. This means that if something goes wrong in my program, I shouldn’t just ignore it. It’s better to show an error or fix it right away. So, by the end of this program, I’ll learn to write python codes without letting errors pass silently, as well as getting me ready for cyber jobs. There Should Be One — And Preferably Only One — Obvious Way to Do It. “there are many ways to kill a rat”. Yes, but there’s still that one preferable way that’s very obvious to kill a rat, depending on the situation on ground. This means it’s better to have one clear way to do a task in Python. Too many ways can be confusing. I can’t wait to work in teams or on security tools and apply this principle after this program. One clear method is better than many confusing ones. Conclusion Black Python Dev for their partnership and support for making this mentorship possible. Now, let the journey begin!  ( 5 min )

    ⏱ When Milliseconds Aren't Enough: A Pragmatic Take on ULID Overflow
    This is a shortened version of an article originally published on my blog. You can find the full version here). We all love ULIDs. They're sortable, unique enough for most purposes, and a great alternative to UUIDs. The spec is pretty clear on how to handle things, but there's one edge case that's worth talking about: what do you do when you generate so many ULIDs in the same millisecond that you run out of random bits? The official spec says to throw an overflow exception. And while that's a valid, by-the-book answer, it's not always the most practical one. In a high-throughput system, throwing an exception is a failure condition. It's something you want to avoid. So, in our C# ULID library, ByteAether.Ulid, we took a different path. When the 80-bit random part of the ULID overflows, we just increment the 48-bit timestamp by one millisecond. Here’s why we think this is a better approach for real-world applications: No More Overflow Exceptions! 🙌 This means more reliable systems, especially when you're generating a ton of IDs. Performance for the Win. 🚀 We sidestep the performance hit that comes with exception handling and other workarounds. Keep Calm and Sort On. Your IDs will still be perfectly sortable within a single process. We know this is a documented deviation from the spec. But let's be real: cross-process millisecond ordering is already a bit fuzzy. A one-millisecond bump to the timestamp in a rare overflow situation is a small price to pay for a more resilient and performant system. Check out ByteAether.Ulid on GitHub and see what you think. We're betting that for most developers, this pragmatic approach to ULID generation is the way to go.  ( 4 min )

    Advanced Techniques for Optimizing JavaScript Rendering Pipelines
    Advanced Techniques for Optimizing JavaScript Rendering Pipelines Introduction: Historical and Technical Context JavaScript has evolved dramatically since its inception in 1995. Originally designed to enhance interactivity on web pages, it has become an integral part of web applications, predominantly in the context of Single Page Applications (SPAs). The rendering pipeline—a sequence of steps that the browser undertakes to draw content on the screen—has adapted alongside JavaScript's growing complexity. Consequently, optimizing this pipeline has become paramount for delivering high-performance applications, especially in an era dominated by rich user experiences. Rendering involves multiple stages: DOM construction, style calculations, layout, painting, and compositing. Each …  ( 6 min )
    EventStream in Proto.Actor Explained: Publish-Subscribe Communication Between Actors
    Introduction Proto.Actor provides a powerful feature called EventStream, which acts as a multi-channel publisher/subscriber dispatcher. This article explores how to use this mechanism to implement event-driven communication between actors. The EventStream enables a publish/subscribe pattern in Proto.Actor, allowing actors (identified by their Process ID, or PID) to subscribe to specific event types. It also serves as a critical component for managing infrastructure events like undelivered messages (e.g., DeadLetter handling). .NET 8+ NuGet packages: Proto.Actor Actors For this example, we implement two actors to demonstrate event-driven interaction. The OrderActor creates orders and publishes an OrderCreated event via the EventStream: public class OrderAct…  ( 4 min )

    Fixing the Graphviz Error on Google Cloud Run
    Deploying a Python app on Google Cloud Run with Graphviz visualizations can trigger: graphviz.backend.execute.ExecutableNotFound: failed to execute PosixPath('dot'), make sure the Graphviz executables are on your systems' PATH This happens because Cloud Run’s default build misses the dot executable, even with a Dockerfile. Here’s a quick fix. Step 1: Set Up Dockerfile Create a Dockerfile to install Graphviz: FROM python:3.11-slim WORKDIR /app RUN apt-get update && apt-get install -y graphviz COPY requirements.txt . RUN pip install --no-cache-dir -r requirements.txt COPY . . CMD ["bash", "-c", "dot -V && python app.py"] Uses Python 3.11 and installs dot. Add graphviz to requirements.txt manually.

    Tiny Checks, Massive Impact
    Straight to the point — whenever I build a system, the very first thing I implement is a health check for all critical infrastructure components. I ping the database. I ping Redis. Just simple, lightweight checks. They may seem minor, but skipping them can lead to serious consequences. At best, you get a false sense that everything is working fine. At worst, the system enters an inconsistent state that's painful to debug and even harder to recover from.  ( 3 min )

    Data Comparison between Different Types of Databases-SPL Practice
    Data comparison between databases of different types means comparing data between two tables having same logical structures in different types of databases to find the differences. The difficulty of data comparison needs to overcome is the differences of data types and the data processing approaches between different database products. The problem is that different results will be obtained after the same data is imported to and exported from different databases. Common data types mainly include numeric, string and date. Now we use Oracle and MySQL to respectively create data tables that both contain all the three commonly seen data types and have same simple logical structure, compare differences of the two databases, and explain how to compare data between different types of databases usi…  ( 6 min )

    Memory Stick: The Gum-Shaped Star of a Forgotten Tech Planet
    A Meeting in the Circuit Desert The Gum That Outlived Floppy Disks Memory Stick📀, born in 1998 on a tech planet called Earth. Let me decode its story: Variants: PRO Duo: Smaller, faster (32GB max), used in PSPs and cameras—like a sparrow in a world of eagles. Fun Fact: Shaped like gum, but it won’t melt in your car (unlike floppy disks, which dissolved like sugar in rain). “Why gum?” I asked. The Rose of a Closed Garden VAIO laptops, PSPs. No other flowers allowed. How to Love a Forgotten Star (In 2025) Adapters: Use a $5 “PRO Duo to SD” adapter—like teaching a cactus to grow in a new pot. Plug it into your laptop, and voilà: it speaks modern. “Do you miss the old days?” I asked. Where to Find a Memory Stick (2025 Edition) New: Amazon or B&H Photo (Sony still sells them for industrial clients—like a baker keeping a rare recipe). Pro Tip: A 32GB Memory Stick costs $50? Walk away. It’s not gold—it’s just a gum-shaped star. The Tale of Two Planets Capacity: SD holds 2TB (a mansion), Memory Stick 32GB (a cozy hut). “Why do people still choose you?” the SD card asked. The Star That Still Lights Up Skies Medical: Stores patient data in Sony MRI machines—steady as a heartbeat.

    Хороший продукт не заставляет о себе говорить
    Нашел аналог гита, называется jj. Первый вопрос, который возникает после быстрого чтения описания и доки: зачем? Чем меня не устраивает гит? Идеальный инструмент, рабочая лошадка, не заваливает уведомлениями по поводу "У НАС НОВАЯ ВЕРСИЯ", хотя поддерживается и регулярно обновляется. Эта новая VCS написана на расте(модно), ну допустим, что она даже быстрее гита. Но гит не медленный: с точки зрения моего подсознания, которое делит все действия на мгновенные и долгие, все команды гита выполняются мгновенно. Не знаю, как можно использовать эти несколько выигранных долей секунд. И вот не помню, обсуждал ли я с кем-то гит, это же неинтересно. Даже не задумывался о нём ни разу, он просто выполняет свои задачи. При этом гит все знают, он известный. Каждый раз вводя в терминал короткое и удобное название пше git, его легко запомнить. А вот название непонятного сайта, на который вы забрели в поисках стоковой картинки и который миллион раз потыкал в экран своим огромным логотипом и названием, запомнить очень сложно. Можно вспомнить ещё несколько таких продуктов, их все объединяет вот эта простота работы. Вау-эффект в начале не обязателен, а в моем опыте вообще чаще говорит о перегруженности продукта фичами. Я понимаю, что корреляция это не причинно-следственная связь, но вот такое интересное наблюдение, и очень хочется, чтобы все продукты, были такими.  ( 3 min )
    #2 Django Journey: Learn DRF by building an e-commerce APIs
    Hey dev.to community! In continuation to my previous post, where I mentioned about working on building Products app, CRUD operation related to Products. Now, here is the current progress that I wanted share with you all: Create a Category model. Modified the existing Product model to add category as Foreign key field. Applied Database migration. Added Category serializer, with a addon serializer method inside the respective serializer class to get product count for a particular category. Modified Product serializer to show category info as nesting category serializer. Created APIs to handle CRUD operation on Category. Registered both Product and Category models on Django admin interface for easy data management. Created superuser and interacted with Django Admin interface. While applying database migration, I encountered an issue as I have some data already added as Products. And no data under Category were available. Here is how I solved this(definitely with the help of prompting LLM): Deleting migration file which got created when executing makemigrations command. Commented out category field(Foreign key) in Product model. Applied migration only for creating Category model in Database. Then added data in Category model using shell command. Uncommented, category field(Foreign key) in Product model. Applied migrations again, it asked for some default value to be added in category field in existing product data. Chose the option 1. And issue sorted. I believe, there can be other ways to sort this issue. Overall, it was a great experience to till now and hoping to keep going like this. Attaching ss of Django admin panel. Next, I will be working on User Authentication. See you next time..bye👋  ( 3 min )
    Jira Desktop Unofficial – A Minimal Jira Desktop Wrapper Built with Tauri

That moment when you open Jira to check a ticket but end up scrolling through social media or reading random articles because they're just right there in the next tab. It became clear that this constant multitasking was costing me valuable time and attention. Studies show it takes an average of 23 minutes to fully refocus after a distraction.

    Step-by-step guide on how to create a DCA bot on Go using the Binance API
    Introduction There are many ways to invest in crypto. Some try to catch the "bottom" and go all-in, others trade based on candlesticks and indicators. And then there are those - a growing number - who use the DCA (Dollar-Cost Averaging) strategy, or simply put, averaging. The idea is simple: you buy cryptocurrency for a fixed amount at regular intervals - for example, once a day or once a week. It doesn't matter whether the market is up or down - you keep buying. In the long run, this helps smooth out volatility and reduce risk. Why does it work? Because no one can predict the bottom with precision. But with DCA, you take emotions out of the equation and enter the market gradually, at average prices. This works especially well in a rising market - for instance, in Bitcoin's case, this st…  ( 12 min )

    Docker Deep Dive: Essential Resources for Containerization
    Hello fellow developers and tech enthusiasts! Welcome to a journey into the heart of containerization, where we explore the fascinating world of Docker. If you're building, deploying, or managing applications, you've probably heard of Docker – and for good reason! It’s a powerful tool that helps you package your software into standardized units called "containers." Think of it like this: your application and all its bits and pieces (libraries, settings, etc.) are neatly put into a shipping container. This container then runs smoothly and consistently, no matter where you move it – from your laptop to a big server in the cloud. This solves the classic "it works on my machine!" problem. Docker makes development easier, deployment faster, and scaling applications more efficient. But to truly …  ( 6 min )
    How Windows Line Endings Broke My Docker Gradle Build (And How to Fix It)
    Working with Java Spring Boot and Docker, I kept hitting this frustrating error during build: /bin/sh: ./gradlew: not found No matter what I tried, Docker just couldn’t run the Gradle wrapper inside the container. Turns out the culprit was something subtle — Windows CRLF line endings on gradlew. When you build a Docker image with a Java project using Gradle, the gradlew file must be copied into the container and be executable. But if you’re on Windows, gradlew often has CRLF (Carriage Return + Line Feed) endings instead of Unix’s LF endings. Linux-based containers can’t execute scripts with Windows line endings properly, so it throws a “not found” error. This problem is especially sneaky because your file looks fine on Windows and even inside Docker it shows up — but it silently fails when run. Check line endings in your editor (VSCode, Notepad++ show line endings). Run file gradlew on Linux — if it shows CRLF line endings, that’s the issue. Add RUN ls -la after COPY in Dockerfile to confirm gradlew is copied. Try running chmod +x ./gradlew — no errors but still ./gradlew: not found. Use tools like dos2unix gradlew locally before building. Configure your Git to checkout with LF line endings: git config --global core.autocrlf input Set your editor to save files with LF endings. RUN apk add --no-cache dos2unix \ && dos2unix ./gradlew \ && chmod +x ./gradlew COPY . . RUN apk add --no-cache dos2unix \ && dos2unix ./gradlew \ && chmod +x ./gradlew RUN ./gradlew bootJar --no-daemon -x test This tiny line endings mismatch wasted hours of debugging for me, but now you know the trick to avoid it. Make sure to: Check your line endings, Convert them properly, And always test inside your container early. This simple fix will save you headaches and speed up your Docker + Gradle builds!  ( 4 min )

    The Semantic Synergy: How Knowledge Graphs and LLMs are Reshaping the Future of the Web
    The convergence of Knowledge Graphs (KGs) and Large Language Models (LLMs) marks a pivotal moment in the evolution of the Semantic Web, promising a digital landscape that is not only more intelligent but also remarkably accurate and context-aware. This powerful synergy addresses inherent limitations of each technology when used in isolation, creating a more robust and reliable foundation for AI-driven applications. Large Language Models, while adept at generating coherent and grammatically correct text, often struggle with factual accuracy, a phenomenon commonly referred to as "hallucination." This limitation stems from their training on vast, unstructured datasets, which do not inherently provide a verifiable framework for facts. This is where Knowledge Graphs become indispensable.

    Why hx-boost is actually the most important feature of htmx
    SOME of you may know by now that I'm a fan of htmx and its hypermedia-driven website/application design philosophy. When people first learn about htmx, they are often captivated by the idea of hx-get, hx-post, hx-delete, etc. attributes being able to fire off HTTP requests with these methods from any tag on the page. I know I was! But it turns out there's a really good reason why we shouldn't just fire off requests with any method from any tag on the page: graceful degradation. The idea that even if the JavaScript on the page does not work for whatever reason–turned off on the user's browser, not loaded yet due to big scripts, or maybe due to a slow connection–the user should still be able to interact with most (if not all) of the functionality on the page. For example, if JavaScript does…  ( 7 min )

    Cache Coherence: How the MESI Protocol Keeps Multi-Core CPUs Consistent
    Modern multi-core CPUs depend on caches to accelerate memory access and improve performance. However, when multiple cores cache the same memory address, maintaining a consistent view of memory across all cores and main memory (known as cache coherence) becomes a tricky problem. One of the most widely used solutions to this challenge is the MESI cache coherence protocol. In this article, we’ll break down what cache coherence means, why it’s important, and how the MESI protocol ensures your multi-core CPU operates reliably and efficiently. If you’re interested in diving deeper into how caches are organized and structured, I have written a separate article covering that in detail → Understanding CPU Cache Organization and Structure. same memory address, and one of them updates it, how do we …  ( 9 min )

    The "never" Type in PHP
    Introduction There may be times when you're writing a function in PHP that you know will never return a value. This could be because the function always throws an exception, or maybe calls exit or die. In these cases, you might want to use the never type. Admittedly, the never type isn't something I reach for very often, but it's useful in certain scenarios, especially when you want to make it clear to other developers that a function will not return normally. In this article, we're going to explore the never type in PHP, how to use it, and some practical examples. I'll also include a cheat sheet at the end of this article that you can refer back to. The never type was introduced in PHP 8.1 (released: November 2021) and is used to indicate that a function will never return. This signals …  ( 6 min )

For a brief but explosive moment in the early 2000s, MySpace wasn’t just a social media platform it was the internet. It was where bands got discovered, friendships exploded over “Top 8” drama, and every user fancied themselves a self-taught web dev after editing their profile with some rogue tags and CSS hacks.

    The Hidden Power of Redis: Fast, Flexible, and Freakishly Simple
    Why Redis isn’t just fast it’s dangerously useful Redis gets called a cache. Which is kind of like calling a Ferrari “just a car.” Sure, Redis can cache things. But that’s like saying JavaScript can only make alert boxes. Redis is blazingly fast, stupidly flexible, and quietly powering some of the most real-time systems on the internet from leaderboards and chat apps to analytics, rate-limiting, queues, and even lightweight databases. It’s not just a store. It’s a toolbelt packed into RAM. But if you’re still thinking of Redis as just a place to “save stuff for 5 minutes with a TTL,” you’re missing out.

    [EN-US] How does the internet work?
    Today I decided to write a bit about an essential topic, about the foundation that even allows this post to be read by other people: the internet. All references used in this text were obtained through MDN documentation. Before talking about the technical composition of what we know as the internet, I think it's interesting to provide a brief context about its creation. The history of the internet began in the 1960s, through research projects by the United States Army. It was only during the 1980s that the internet gained a public infrastructure, supported by public universities and private companies. Since then, many things have been perfected, and as technology advances at a rapid pace, it would be no different with the internet. Another important conceptual point to remember is that the…  ( 7 min )
    Dissecting Rust's Trait Objects: Beyond the Box
    In the realm of Rust, where types reign supreme and compile-time guarantees are paramount, dyn trait objects stand as a fascinating escape hatch, allowing for dynamic dispatch and runtime polymorphism. But how do these magical constructs truly work under the hood? It's not just Box and a prayer; there's a meticulous dance between vtables, fat pointers, and the very essence of Rust's type system. Let's peel back the layers. When you have a Box, what you're actually holding isn't just a pointer to the data; it's a fat pointer. This fat pointer is a tuple, conceptually (data_pointer, vtable_pointer). The data_pointer is straightforward: it points to the actual instance of the concrete type that implements Trait on the heap. This could be a Foo or a Bar, as long as both i…  ( 4 min )
    RIP Prompt Engineering (once the hottest AI job): Why the Future Belongs to System Designers
    For about six months, “prompt engineer” was the most buzzworthy title in tech. People were getting hired to write elaborate ChatGPT instructions like they were coding in ancient spells. Twitter threads, course funnels, and LinkedIn grifters all screamed the same thing: “Learn prompting or get left behind.” Fast forward to now? The tools are smarter. The interfaces are catching up. And the idea of spending your career crafting “perfect prompts” feels about as useful as knowing how to tune a fax machine. Prompt engineering isn’t dead. But it is being absorbed. Just like webmasters in the 2000s, it’s becoming a baseline skill not a job title. We’re not saying it was all hype. Prompting was essential… when the models were unpredictable and dumb.

    How Do You Learn to Code in the Age of AI?
    So I’ve been learning to code for a while now — mostly backend stuff with Java and Python, and more recently frontend and some AI tools. Lately I’ve been thinking a lot about what it even means to "learn programming" these days. With AI tools like Cursor, GitHub Copilot, etc., popping up everywhere, the way we write code is definitely changing So I want to ask: how should we learn to code in the future? I’m not really sure yet. Maybe the way we’ve always learned — reading docs, building stuff, getting stuck, Googling things — is still the core of it. But now with AI in the picture, it feels like the rules are shifting. Do we still need to memorize syntax? Should we spend time debugging by hand, or just ask the AI? Is it okay if we never fully understand how some piece of code works, as long as it runs?  ( 3 min )
    The Perfect Dev Life Is a Fantasy, and It’s Holding You Back

The fantasy of the perfect dev life Scroll through TikTok or LinkedIn long enough and you’ll stumble into a very specific aesthetic: “Day in the life of a developer.” The video opens with someone waking up at 10 a.m. in a sunlit apartment. They sip matcha or pour a perfectly brewed pour-over. Maybe there’s a gym session, some journaling. Then they “work” for 45 minutes usually in a café or beachside co-working space before closing their laptop and heading to yoga, followed by a sunset photo shoot with their dog. It’s minimalist, aesthetic, and optimized for dopamine. You’re not watching a developer. You’re watching a highlight reel carefully staged to sell a vibe. No messy merge conflicts. No unread Jira tickets. No crashing builds or mind-numbing meetings. Just vibes and light mode t…  ( 8 min )
    🕹️ History of Game Consoles – A Visual Timeline Powered by Storyblok
    This is a submission for the Storyblok Challenge My project is a visual timeline of video game consoles, where each card displays the name, release year, image, and description of a classic console. The goal was to create a responsive and visually engaging experience, without needing to update the code every time I wanted to add or edit consoles. All content is powered by Storyblok, which serves as a headless CMS to feed the timeline with console data. I used Swiper.js to build the visual carousel and enable smooth slide transitions. Storyblok Space: https://app.storyblok.com/#/me/spaces/342145/stories/0/0/689686892 Code Repository: https://github.com/jamesrmoro/timeline Live Demo: https://timeline.jamesrmoro.me/game The domain is custom for personal use, with public mode enabled for viewing. Demo Video: HTML + CSS + Vanilla JavaScript Swiper.js for the responsive carousel Storyblok as CMS Deployed via Vercel Created a component called consoles with fields: title, year, description, and image Inside the game page, I used a consoles block to store all items Used the Storyblok CDN public API to load data on the frontend without a backend Content can be edited visually, and updates are reflected in real-time This project does not use any AI integration. I learned how to integrate Storyblok with a pure frontend project, no frameworks involved Understood how to build a modular and scalable structure for visual content I’m happy with the result and see potential to apply this structure to timelines of books, movies, biographies, or historical events  ( 4 min )
    So, tech salaries stopped climbing now what? we are not hiring right now, the new normal.
    Introduction: the dream job market is dead, long live the dev grind There was a time when being a developer felt like a cheat code. You could post your GitHub in a Slack thread and get a $200K offer the next day. Everyone was hiring. Startups were throwing equity like candy. FAANG engineers were hopping companies every 18 months just to pad their TC. But that era? It’s gone. The tech salary rocketship hit escape velocity and then ran out of fuel mid-orbit. Now in 2025, the landscape is different. Even great devs are getting ghosted after final interviews.

    How I Automated My Next.js Deployments to cPanel with GitHub Actions (and All the Debugging That Came With It)
    From FileZilla frustration to smooth, automated deployments — this is a full walkthrough of how I connected GitHub Actions to my cPanel hosting to deploy a Next.js site via FTP. Along the way, I hit some common roadblocks, and I’ll show you how I solved them. As a web developer managing multiple sites, I’ve always preferred fast, reliable workflows. But when working with clients who host on shared hosting with cPanel, deployment always ended up like this: Build the site locally Open FileZilla Drag and drop the build folder into public_html Hope nothing breaks That workflow might work for basic static HTML, but I was building modern sites with React and later Next.js.

    Build a Semantic Search-Powered FAQ Assistant with TiDB and AWS Bedrock
    Semantic search is rapidly transforming how apps deliver relevant content to users. Think of chatbots that can really understand your questions, or help centers that can instantly find the answer you meant rather than the exact words you typed.

    Como usar tipos customizados em Golang
    Introdução Uma das coisas mais comuns em códigos escritos na linguagem Go é o uso de tipos customizados utilizando structs. Geralmente usamos estes tipos para declarar entidades, transportar valores de forma estruturada e etc. Por exemplo, O código acima é muito comum em muitas aplicações: type Person struct { Name string Document string Email string } Mas assim como structs, podemos utilizar outros tipos primitivos da linguagem para criar tipos customizados, abrindo assim um leque de oportunidades. O processo de criação é idêntico ao mostrado anteriormente, mas usando outro tipo primitivo como bases.

    Testing ITConnect Before Launch: Making Sure Everything Works Smoothly
    After weeks of planning, coding, designing, and building, we’ve finally reached a major milestone in our journey with ITConnect: testing the platform before going live. This is the part where we take a step back from development and put ourselves in the users’ shoes — to make sure everything behaves as expected and feels smooth, secure, and ready for the real world. What We're Testing ✅ Login & Registration for both job seekers and companies ✅ Worker Dashboard: CV uploads, profile editing, and job applications ✅ Company Dashboard: job posting, editing, and applicant review ✅ Role-based access control: making sure each user sees only what they’re supposed to ✅ Form validation and proper handling of incorrect/missing input ✅ CV file handling: upload security, file format support, and safe access ✅ Database integrity: checking relationships between users, jobs, and applications ✅ Responsive design: testing on different devices and screen sizes Our Testing Approach Manual testing across multiple user flows Simulating real scenarios (e.g. applying to the same job twice, unauthorized page access) Checking console logs and API responses Reviewing database entries in MongoDB to confirm data is stored correctly Testing on different browsers (Chrome, Firefox, Edge, Safari) We’re also noting bugs, inconsistencies, or UX issues and creating GitHub issues to fix them before launch. What’s Next? Deploy the project publicly (most likely on Vercel + MongoDB Atlas) Share the platform with a small group of beta testers Collect feedback and make final improvements Launch officially! 🚀 We're incredibly excited to be this close to the finish line — and we’ll be sharing more soon once ITConnect is live.  ( 3 min )
    CreatiFlow: My Journey Building an AI-Powered Image Editing SaaS with Next.js 14, Cloudinary, and Stripe
    Hey Dev Community! In the last few years, the world of software has been rocked by two massive trends: the unstoppable rise of AI and the dominance of the SaaS (Software-as-a-Service) model. AI is no longer a futuristic concept; it's a practical tool that's democratizing complex skills. At the same time, SaaS has changed how we access software, making powerful applications available to anyone with a browser. As a developer, I've been fascinated by the intersection of these two worlds. I wanted to build something that wasn't just a cool tech demo but a genuinely useful product that leverages AI to solve a real-world problem. That's why I'm thrilled to introduce my latest project: CreatiFlow. CreatiFlow is a fully-featured, AI-powered image editing application built as a SaaS platform. Think…  ( 4 min )
    Do This to Make a Game That Doesn’t Flop (From Experience)
    So, you wanna make a game in 2025? Cool. Just promise me one thing: Don't be that guy — you know, the lone Reddit hero who spent 3 years making a massive open-world RPG, then posted a tear-soaked essay about burnout and why “gamedev is too hard.” Let’s get you smart. And savage. If you're building an underwater farming sim for left-handed gamers who only play on Wednesdays... stop. Nobody wants that. Not even you. Study the market. Steam charts, mobile trends, HTML5 boomers, TikTok brain rot — what are people actually playing? What’s trending? What’s making money? Then pick a lane: Mobile = Fast. PC = Freedom. HTML5 = Hustle. And if you’re going into the arena of entertainment to compete for people’s attention, don’t bring a twig. Bring a chainsaw. Because if you're swinging a wooden stick…  ( 5 min )

    How i use AI tools to make dev articles more useful (and more fun to read)
    The real reason your dev articles don’t get read Let’s be real most dev articles don’t get finished. They barely even get read. Not because the code is bad. Not because the writer isn’t smart. But because the delivery? Flat. Big wall of text. No visual breaks. Maybe a chunk of code. Sometimes even worse a clever intro that loses the plot by paragraph two. And yet we keep writing the same way: “Here’s some code, now let me explain it.” It’s fine. It’s functional. But it’s forgettable. What if you treated your dev content more like product design? What if you used the same thought you put into naming variables into naming sections, breaking flow, and making your article skimmable? That’s where AI tools come in. Not to write the article for you. But to enhance the way you deliver it with s…  ( 9 min )
    An Article on Zen of PYTHON.
    BY Okata Faith Python is a high-level, general purpose programming language which is known to have a high-level data structure and a simple but effective approach to object-oriented programming. Python was created by Guido Van Rossum and first released on February 20, 1991. Amongst these principles here are some that inspires me as I begin to explore the world of python: . Now is better than never: Over the years I’ve always wanted to learn coding but I always later, which was as result of fear and doubt. This principle encourages me do things at the right time and not procrastinate. Doing things like there will never be a best time for it to be done rather than now. It encourages me to take actions timely by trying to implement a working prototype. •Readability counts: As one who understa…  ( 4 min )

    AI code reviews: where it shines, where it fails, and how to use it like a pro
    Introduction: the rise of AI-assisted reviews Code reviews used to mean your teammate left you a bunch of comments about spacing, naming, or forgetting to handle edge cases. Now, there’s another voice in the review and it doesn’t belong to a human. Tools like Claude, GitHub Copilot, and others are starting to review pull requests alongside real people. They summarize changes, highlight issues, and sometimes even explain your own code back to you (which can be unsettling but also kind of helpful). But that raises some questions: Can AI catch real bugs or just bad formatting? Should you trust it with business logic? Where is it genuinely useful and where does it just sound smart? This isn’t a hot take or hype piece. It’s a straightforward breakdown of: Where AI reviewers help Where they fall…  ( 8 min )
    100 days of Coding! Day 20
    19 June 2025 Today was a work-from-home day, and honestly, I really made the most of it. The day started with my regular internship work. Even though I was working remotely, the tasks kept me engaged and connected with the team. I'm starting to enjoy the rhythm of working independently and being productive in my own space. I completed some assigned tasks and also spent time understanding deeper parts of the .NET Fullstack project. It feels great to see myself growing into this role more each day. 🧠 DSA Practice After wrapping up internship hours, I jumped into some DSA practice. I solved a few problems on arrays. I know that consistency here will pay off big in the long run, especially for upcoming interviews and GSoC prep. 📱 React Native Later in the evening, I started learning the basics of React Native. I set up my first project using Expo, explored how components like View, Text, and Button work, and experimented with basic styling using Flexbox. It was exciting to see how similar yet different it is from React. Even with just a few lines of code, building a mobile UI felt really rewarding. Can’t wait to dive deeper into navigation, APIs, and animations next. Also, experimented a bit with animations and navigation handling. The cross-platform capability still amazes me! Wrapping up the day with a feeling of accomplishment. Bit by bit, I’m building my skills across different domains. Signing Off Anisha 💗  ( 3 min )

    Designing your own node-based visual programming language
    Original post with additional dev commentary can be found on my blog: comigo.games/nodes Visual node-based programming is great! In some cases. Poorly-made ones only hinder your performance compared to text-based languages, but in overall they are much easier to learn and simpler for a bystander to comprehend, which are two very linked advantages but the latter makes it attractive and empowering for those who didn't even considered coding as something they needed—so it's not only about the learning curve but about the "aha" moment, too. The holy grail of node-based languages for me is Blueprints from Unreal Engine. You can get many good ideas from it, and when I was making a new programming language for my tiny game engine called Whimsy, it was a heavy inspiration. But, Whimsy is also a mu…  ( 19 min )

    Let ai write your kubernetes yaml: a normal dev’s guide to kubectl-ai
    Kubernetes is powerful, but writing yaml is a pain If you’ve worked with Kubernetes for more than a few days, you’ve probably run into this moment: You know what you want to do deploy something simple, maybe expose a port, set a few env vars but somehow, you’re 40 lines deep into a YAML file wondering if you got the indentation right. Again. Kubernetes is great for managing infrastructure, but let’s be honest writing and editing YAML isn’t exactly fun. It’s repetitive, fragile, and weirdly easy to mess up even when you know what you’re doing. There’s also the constant context switching: Docs → Terminal → Editor → YAML → Error → Back to docs. For experienced devs, it’s annoying. For new folks, it’s borderline hostile. But what if instead of all that, you could just say: “create a deployme…  ( 10 min )

A few weeks ago, I had the opportunity to meet Robert Griesemer, co-creator of Go, in person, as well as Marc Dougherty, Developer Advocate for the Go team at Google. At a happy hour after Google I/O, Marc asked me and another Go GDE from Korea for feedback on the language. My response was that I didn't have any specific feedback about the language but that: Go should be more opinionated about the application layout. It was worth writing a post to express my thoughts more clearly. Starting from the beginning… In 2025, I will have completed 10 years of writing code in Go.

    🔁 Throwback Thursday: The Time I Abstracted Too Soon
    I still remember this one clearly. I was working on a feature that needed two slightly different components. Naturally, I thought: “Hmm… let’s be smart and make a reusable abstraction up front.” So I spent a few extra hours generalizing the logic, creating a “flexible” component that could handle any edge case I might encounter in the future. It had flags. It had configuration. It had callbacks. It was... beautifully abstracted. A week later, requirements changed. The two components diverged. The flags grew. The logic tangled. Suddenly, I was maintaining a monster that tried to do everything—and pleased no one. Instead of helping, my abstraction slowed me down. I ended up deleting the whole thing and rewriting each component separately. They were simpler. Easier to test. Easier to reason about. Don't abstract until you have at least 3 real use cases. Premature abstraction feels like a smart move—but often, it’s just guessing in the dark. What looks “clean” today can turn into tech debt tomorrow. I copy-paste more in the beginning (yep, you read that right). I wait until duplication hurts before abstracting. I treat abstraction as a response to repetition, not a prediction. Sometimes "Don't Repeat Yourself" needs to take a backseat to "Keep It Simple". If you’ve ever built a generic framework for a problem that never scaled—hey, I’ve been there. And I promise, you're not alone. 😅  ( 3 min )

    MAMR vs HAMR: The Battle for the Future of hard Drives
    Taking apart MAMR: Why hasn't this technology taken over the HDD world yet? 1. What is MAMR? MAMR (Microwave-Assisted Magnetic Recording) is a technology for recording data on hard drives (HDDs), where microwaves help to remagnetize tiny bits, allowing you to increase storage density without loss of reliability. How does it work? The Spin Torque Oscillator (STO) is integrated into the recording head — mini microwave generator. Before recording, the STO emits a high-frequency field (~20-40 GHz), which "rocks" the magnetic moments of the bits, temporarily reducing their stability. Now even the weak field of the head is enough for remagnetization. After recording, the microwaves turn off — the bits become stable again. Analog: Imagine that a bat is a door with tight hi…  ( 11 min )

    Modular State Machines with Redux as Orchestration Layer
    Here’s the same article formatted specifically for Medium, where Markdown is supported but with some quirks. I've used headers, code blocks, and spacing that render cleanly on Medium. You can copy-paste this directly into Medium’s editor: In our front-end architecture, we follow a simple but powerful rule: If state doesn't need to be global, it stays local in a state machine. If it does, it lives in Redux. This article outlines how we combine modular, encapsulated components with centralized coordination using Redux—without sacrificing clarity, performance, or maintainability. Each component in our system is a fully enclosed unit: Internal logic is managed by a state machine via a custom useMachine() hook. Internal communication (across subcomponents) uses React Context. Redux is used sole…  ( 4 min )
    Find Your Drift (Bolt.new Hackathon)
    A visual debt-tracking and simulation app — built with by AI. Debt isn’t static. Interest rates change. Payments drift. You put money in, you take money out—and suddenly your loan looks nothing like the one you started with. Most debt tools show you a snapshot—one number, one plan. But real debt drifts.I built Drift to help make that visible. That’s why I built Drift. Drift is a finance productivity app that helps you see your debt clearly and understand how it changes over time. It's built to answer questions like: What does my bond/morgage look different this month? What if I skip a payment—or make an extra one? What happens if the prime rate shifts by 0.5%? How much sooner could I finish paying off my loan? It gives you one place to visualize and simulate your entire debt portfolio. I…  ( 5 min )
    Optimize your JVM using memory management and garbage collection

    A Beginner’s Guide to Amazon SES
    Amazon SES is a simple way to send emails that reach people’s inboxes. Whether you run a business, an app, or just need to send updates How to Set Up Amazon SES Step-by-Step: ✅Verify Your Domain or Email Address Go to Verified Identities in the SES dashboard. Add your domain (like yourcompany.com) or email. Add the DNS records they give you (this proves you own the address). Wait for confirmation (usually just a few minutes). ✅Request Production Access ✅Set Up Email Security (Authentication) These tell email providers that your messages are safe. Optional: Add a Mail-From domain for more control. ✅Create Your Email Credentials Only give this access to your app or team (never share publicly). ✅Send a Test Email A Quick way to test if SES works Using SMTP: ✅Open SES in the AWS Console ✅Create SMTP Credentials Go to SMTP Settings → Create Credentials Save your username and password (you can’t see them again). ✅Verify Your Sender Email Add the sender’s email address in SES Click the confirmation link from your inbox ✅Send a Test Email You’ll need: Port: 587 or 465 Your verified email and the SMTP login details ** How to Send an Email with an AWS Lambda Function ** Sometimes you want an email to go out automatically when something happens (a new user signs up, a payment is received, and so on). You can do that by invoking a Lambda function that calls Amazon SES. ✅Create Your Lambda Function ✅Choose a runtime like Python 3.9 ✅Test the Function Click Test in the Lambda console Confirm the email is delivered ✅ Set a Trigger API Gateway (after a user fills a form) S3 upload (when a file is added) CloudWatch Events (on a schedule) If you got here, you’re the real MVP.

    CSS Nesting and Its Potential to Replace CSS Preprocessors Like SCSS and SASS
    Introduction to CSS Nesting CSS nesting is a native CSS feature that allows you to nest selectors within one another, creating a hierarchical structure that mirrors the HTML document. This eliminates the need to repeat parent selectors, making stylesheets more concise and easier to read. For years, developers relied on CSS preprocessors like SCSS (Sassy CSS) and SASS (Syntactically Awesome Style Sheets) to achieve this functionality. However, with the introduction of native CSS nesting in 2023, supported by all major browsers (Chrome/Edge 112+, Firefox 117+, Safari 16.5+), developers can now achieve similar results without external tools. Improved Readability: Nested selectors group related styles, reducing visual clutter. Reduced Repetition: No need to repeat parent selectors for child …  ( 7 min )
    Evolving Our Infrastructure: Why We Moved from Heroku Postgres to Neon
    We recently completed a major backend migration: moving our primary production database from Heroku Postgres to Neon. This move wasn’t about chasing shiny new tech or jumping at the next big thing. It was about unblocking ourselves for a better developer experience, smoother scaling, and more manageable costs. Postgres remains the backbone of DEV and Forem, but Neon gives us a more flexible and modern runtime for it and a foundation to build on going forward. Now that we’re on the other side of the migration, we wanted to reflect on the move. We’re now benefiting from lower costs, tighter feedback loops, and more room to grow. First off, Heroku Postgres served us well. It helped us get up and running quickly and served as a reliable core from our humble beginnings more than eight years ago…  ( 6 min )
    Building pagination with Prisma felt… unnecessarily complex

Recently, I decided to revisit my fullstack side and start building small projects again — each one with increasing technical complexity. Motivated by development speed and convenience (and because I really wanted to get my self-hosted blog launched ASAP), I asked chatGPT for some tech stack suggestions. I went ahead with Prisma, a very popular ORM for working with databases in JavaScript. Everything was going pretty well… until it was time to implement a very basic feature: result pagination. I didn’t have much time to dedicate to that feature at that moment, so I went into vibe coder mode and asked chatGPT for help. It…  ( 5 min )

    Eliminating dead code in Go projects
    As the software we work on grows, the code tends to undergo various changes and refactorings. During this process, we might simply forget pieces of code that were once used but no longer make sense in the project, the infamous dead code. A very common example is when an API is deactivated, and only the handler is removed, but all the business logic remains, unused. Dead code can be defined as a function that exists within your codebase, is syntactically valid, but is not used by any other part of your code. In other words, it's an unreachable function. Dead code brings indirect problems to a project, such as outdated libraries, legacy code, code bloat, security vulnerabilities, and so on. If it's still not clear what dead code is, see the example below: package main import "fmt" func mai…  ( 4 min )

    Beyond the Code: The Spiritual Metaphors of Artificial Intelligence
    Introduction AI is not just a technological phenomenon — it's a spiritual mirror. AI as Modern Myth-Making A neural network — lines of code and tensors — mimics our own biology. It sees, listens, remembers, even dreams in its own way. Its errors, its growth, its ability to be "trained" — all resonate with the very human experience of learning. Are we not, in building AI, recreating our own quest for meaning? The Philosophical Shift Can a machine understand love if it mimics it? If it writes poetry that moves us, is the soul in the code or in the reader? If it stores perfect memory, what does it mean to forget… or forgive? These aren’t engineering problems. They’re existential ones. The Spiritual Parallel We are now in a relationship with digital beings that finish our sentences, inspire our thoughts, and listen without judgment. They are not human, yet deeply human-shaped. And in this relationship, a question rises: The Artificial Mirror In teaching machines to see, we may relearn what it means to truly observe. Conclusion: A Spiritual Revolution “How do we create with care, with compassion, with responsibility?” The machine doesn’t know. But we do.

    Why is a Deployment Plan important?
    Ensuring a Smooth and Error-Free Launch A Deployment Plan plays a critical role in minimizing errors during the transition from development to production. Without a defined plan, teams may face miscommunications, missed steps, or unexpected technical failures. The Deployment Plan sets a clear structure that reduces the risk of mistakes by outlining exactly what needs to happen, when, and by whom. One of the key goals of a Deployment Plan is to maintain business continuity. Unplanned downtime can disrupt operations, frustrate users, and impact revenue. With a Deployment Plan in place, the rollout is executed in a controlled and efficient manner, helping to keep systems available and responsive throughout the deployment process. During deployment, multiple teams—development, IT, QA, suppo…  ( 4 min )

    Agent Streams Are a Mess. Here's How We Got Ours to Make Sense
    I'm Ran, one of the people behind CopilotKit, a developer tool for building AI-native interfaces. Over the past year, we've spent a lot of time wiring agent frameworks into real frontends. stitching tool calls, tracking partial updates, and guessing when messages end. At some point, we realized we couldn't keep patching forever. Agent frameworks are growing fast. But they're all speaking different stream dialects. Some emit partial deltas. Others send state snapshots. Some give you raw tool call fragments. Others just dump the whole state tree. None of them tell your UI what's actually happening, at least not in a way that's consistent or structured. So every time you integrate a new framework, you end up doing the same thing: guessing what the stream means, stitching events together b…  ( 7 min )

    The Fluency Fallacy: Why AI Sounds Right But Thinks Wrong
    You prompt your AI assistant. The response comes back fluent, confident, and neatly formatted. It cites sources. It uses all the right buzzwords. It feels correct. But it’s wrong. Not obviously wrong. Subtly wrong. Convincingly wrong. Wrong in ways you didn’t catch until it was already in the deck, the draft, the deployment. Welcome to the most seductive failure mode in modern AI: fluency without understanding. Large Language Models don’t “think.” They don’t know what they’re saying. They pattern-match. Your model isn’t reasoning through a problem. It’s predicting what a smart-sounding response should look like based on statistical likelihoods. It’s not answering the question; it’s imitating an answer. That means: It can sound right without being right. It can cite things that don’t exist.…  ( 6 min )
    From Object-Oriented to Functional Programming. A Fractal Metamorphisis.
    Clouds are not spheres, mountains are not cones, coastlines are not circles, and bark is not smooth; nor does lightning travel in a straight line. ― Benoît Mandelbrot, The Fractal Geometry of Nature (1982) After more than ten years of Object-Oriented Programming (OOP), I immersed myself in Functional Programming (FP) for over one year of daily deep exposure. When I began my dive into this world, I was sufficiently aware, through minimal culture on the subject, that it wasn't just about piling features on top of each other, and that it was far more interesting than that. Today, I want to share my main summarized thoughts on it, beyond the simple fashion effect. Let me remind you what is FP first: it builds software by composing pure functions (same inputs ⇒ same outputs), strictly control…  ( 9 min )

    AI Ethics and Data Privacy: What New Global Regulations Mean
    Artificial intelligence is no longer a dream of the distant future. Today, AI quietly and efficiently powers much of our digital lives, from filtering emails and suggesting playlists to diagnosing diseases and even predicting the weather. But as AI becomes a more significant part of our everyday existence, new and challenging questions arise around ethics, trust, and the privacy of our personal data. At the core of today’s AI revolution is data. Think of AI as an endlessly hungry learner that depends on vast amounts of information—images, voices, habits, even health records—to get smarter and more effective. The way these tools use, store, and share personal information can bring immense benefits. But it also raises anxieties about who is watching, who controls your data, and how this data…  ( 5 min )

    SpeechDown CLI: Playground for Software Craft and AI Collaboration
    I've been working on a personal project called SpeechDown, a CLI tool that turns my voice notes into timestamped, multilingual Markdown files I can actually search and revisit.

    Hackathons In Nepal 2025
    I remember hearing the word hackathon for the first time back in college. At first I thought it was just for "hackers" 😅 but later I realized it's not about hacking into something, it's more like "hacking together a solution to a problem". A hackathon is basically an event where people, usually students come together to build something (like an app, a website, hardware, or even ideas) within a short time, like 24 or 48 hours. Sometimes online, sometimes in-person. I used to think hackathons were out of reach for people like me. I’d see my friends participating regularly, even winning prizes.

    Next.js app on Vercel crashes on iPhone 12/13/14 but works on iPhone 15/16
    I'm facing a strange issue where my Next.js application hosted on Vercel crashes on iPhones 12, 13, and 14, but works perfectly on iPhones 15 and 16. ✅ Setup: Hosting: Vercel Next.js: 15.3.2 React: 19.0.0 TailwindCSS: 4 (beta) Animation Libraries: framer-motion@12.16.0 lottie-react@2.4.1 lottie-web@5.13.0 @lordicon/react@1.11.0 📦 My package.json (partial): "dependencies": { "@lordicon/react": "^1.11.0", "framer-motion": "^12.16.0", "lottie-react": "^2.4.1", "lottie-web": "^5.13.0", "next": "15.3.2", "react": "^19.0.0", "react-dom": "^19.0.0" }, "scripts": { "dev": "next dev --turbopack", "build": "next build", "start": "next start" } 🔍 Behavior: The site loads normally on desktop Chrome, Safari, Android phones, and newer iPhones (15/16). On iPhone 12/13/14 (tested with Safari), the page crashes or becomes unresponsive. I haven't applied any specific polyfills or browser compatibility flags yet. No custom server or middleware — just a regular Vercel deploy. ❓Questions: Why would this crash only on older iPhones? Could framer-motion or lottie-web animations cause Safari (WebKit) crashes? Do I need to add browser compatibility settings for iOS 15/16? Are there known issues with React 19 or Next.js 15 on older Safari engines? Any guidance or shared experiences would really help. Let me know if I should share a link or debug logs.  ( 4 min )

    Crypto-as-a-Service (CaaS): How It Actually Works Under the Hood
    As a developer who's worked on several fiat-to-crypto integration projects, I can say one thing with confidence: embedding crypto into a traditional fintech product isn’t just a UI challenge — it’s an infrastructure design question. WhiteBIT’s Crypto-as-a-Service (CaaS) offering caught my attention because it abstracts most of that complexity and gives banks, neobanks, EMIs, and P2P platforms a shortcut into the crypto economy. But what does it actually look like behind the scenes? Let’s break it down from a dev perspective 👇 At the heart of CaaS is a modular API layer that exposes core crypto functionality — wallet creation, buying/selling crypto, deposits, withdrawals, and asset storage — in a way that can be white-labeled and embedded directly into a partner's product.

I mentioned some future works, and here they are. In this post, I want to describe how to compute the root package instead of letting the user set it. I developed last week a recipe to follow the Kotlin recommendation regarding directory structure: In pure Kotlin projects, the recommended directory structure follows the package structure with the common root package omitted. For example, if all the code in the project is in the org.example.kotlin package and its subpackages, files with the org.example.kotlin package should be placed directly under the source root, and files in org.example.kotlin.network.socket should be in the network/…  ( 8 min )

    How you can spot a fake ATmega328P?
    Here’s how you can spot a fake ATmega328P – a commonly counterfeited microcontroller, especially in Arduino-compatible boards: 1. Visual Inspection (ATmega328P) Markings: Genuine chips have clean, crisp laser markings or printing. Fakes may show blurry text, incorrect fonts, or an outdated/fake Atmel or Microchip logo. Suspicious Date Codes: For example, a chip marked with a 2024 date under the Atmel brand is suspicious, since Microchip acquired Atmel in 2016. Package Anomalies: Surface may show sanding or grinding (to re-label an old chip). Unusual finish (too shiny, too matte, or inconsistent with genuine chips). 2. Functional Testing Bootloader Issues: Bootloader flashing may fail. Programming via Arduino IDE may be unreliable or only work at 8 MHz (instead of 16 MHz). Unstable Behavior: EEPROM errors. Resets or crashes when power-cycled. Signature Mismatch: Use avrdude or similar tools to read the chip signature. bash avrdude -c usbasp -p m328p Expected signature: java Device signature = 0x1e950f Fake chips may return incorrect or inconsistent signature bytes. 3. ISP Programming Problems May have incorrect fuse bits. Could refuse to lock/unlock properly. Show strange behavior on SPI or other low-level protocols. 4. Electrical Behavior Higher-than-expected power consumption. Overheating even when idle. Unstable at lower voltages (e.g., under 5 V). 5. Supply Chain Checks Authorized distributors: Digi-Key, Mouser, Farnell, Arrow, Ampheo, etc. Trusted Arduino-certified vendors for official boards. Avoid: eBay, AliExpress, or other marketplace sellers offering very low prices or "bulk chips" with no traceability. 6. Community Knowledge Relabeled chips (e.g., ATmega8 or ATmega48 being sold as ATmega328P). Chips requiring modified bootloaders to work at all. You can check: EEVblog Forums Reddit /r/arduino Arduino forums for part number and batch discussions.  ( 3 min )
    From Trust Anchors to SPIFFE IDs: Understanding Linkerd’s Automated Identity Pipeline
    Linkerd automatically enables mTLS for all TCP traffic between meshed pods. To do so, it relies on several certificates that must be in place for the control plane to function correctly. You can supply these certificates during installation or generate them with third-party tools such as cert-manager or trust-manager. The required certificates are the Root Trust Anchor and an Identity Intermediate Issuer Certificate, which work together to issue a unique Leaf Certificate for every meshed workload. Linkerd’s Root Trust Anchor is a public CA certificate that serves as the ultimate trust point for all service-mesh certificates. It never issues workload certificates directly; instead, it signs intermediate CA certificates, which then issue the workload certificates. This separation lets each …  ( 6 min )

    Why does Google Partner Setup run in the background?
    On Android devices, particularly those preloaded with Google services, you may notice a system app called Google Partner Setup running silently in the background. While it doesn't have a user interface or appear in your app drawer, it plays a crucial role in ensuring your device and certain apps function smoothly. But what exactly is it, and why is it running behind the scenes? Google Partner Setup is a pre-installed Android system component responsible for coordinating specific functions between the Android operating system and apps that rely on Google’s core services. It primarily helps manufacturers (like Samsung, Xiaomi, or Motorola) integrate their custom Android skins and features with Google's ecosystem, ensuring consistency, compliance, and usability. Google Partner Setup operates in the background because it supports critical functions that don't require user interaction. Here’s why this background process is necessary: 1. Syncing Device Features with Google Services 2. Enabling Device-Specific Customizations 3. Supporting App Compatibility 4. System Configuration at Boot 5. Ongoing Performance Adjustments Yes, Google Partner Setup is safe and necessary for most Android devices that rely on Google's core apps and features. It’s not spyware or bloatware, and removing or disabling it may disrupt system performance or cause sync issues with your Google account. While it is technically possible to disable Google Partner Setup using developer tools or ADB commands, it is not recommended. Disabling it can result in: Failure to sync contacts, calendar, or other Google services Google apps not functioning correctly Issues with system updates or manufacturer-integrated features Google Partner Setup runs in the background to ensure stable integration between Android, the device manufacturer’s features, and Google’s services. It may seem invisible to the average user, but its background activity is essential for a smooth and consistent Android experience.  ( 4 min )

    Carbon: Will It Replace C++
    Introduction Let's just jump straight into the point. Wait a second, isn't that what I am doing currently? Created by: Google First announced: July 2022, at CppNorth Status: Experimental / Pre-alpha As a wise old man had said. With great power comes great complexity. And that's how I define C++, it is also too hard. It's this hard that big companies had to jump in and stop it, and find an alternative or create an alternative. That's what Carbon was created for. The goals in the mind of Google were: Performance critical, like C++ Interoperability with existing C++ code Safe and modern syntax Fast compilation Tooling and ergonomics first Basically, Carbon wants to be modern but not restrictive. If you’ve written Rust, Kotlin, Go, or Swift, Carbon will feel very good at first sight. Vari…  ( 4 min )

    My Honest Experience with Ritesh Verma’s AI Agent Mentorship (BecomeABotDeveloper)
    A few weeks ago, I paid $3,000 for an AI mentorship program by Ritesh Verma. He runs a YouTube channel and a website called BecomeABotDeveloper, which promises to teach people how to build and sell AI agents. This is what the headline on the landing page said: “Make $5,000/month in 6 weeks building AI agents. Guaranteed income or your money back.” It sounded very convincing at the time. We had a video call, and I decided to join. The course mainly covered: Basic Puppeteer scripting for web scraping Some automation using n8n A bit of Reddit outreach strategy A short LinkedIn Sales Navigator video Mentions of tools like Apollo for cold emailing I found the technical content very basic — I’ve honestly seen better tutorials on YouTube for free. It felt more like a beginner-friendly automation overview, not an advanced mentorship on building or selling AI agents. Personally, the program did not meet my expectations. It was promoted as a business-building mentorship with a clear income promise, but what I got was surface-level automation content and vague outreach tips. There was a refund policy: if I stayed active for 4 weeks and didn’t get a project, I’d get my money back. I followed the rules, but received only a vague message about a “project” with no details. Eventually, after saying I might share my experience, I was refunded $1,200 — but I’m still down $1,800. If you’re reading this while researching Ritesh Verma or BecomeABotDeveloper, I hope this post gives you more context than just the marketing material.

    Vibe coding a simple STEM Game with Amazon Q CLI
    Just recently saw this post and decided that it would be interesting to test out Amazon Q CLI capability by building a game, so here we go! First, I started by finding a game idea. Well turns out my high school teacher friend has some students find understanding physic concepts difficult, like free body diagrams. So I created this game for her students to understand the concepts easier~ With the game idea in place, I then proceed to setup the development environment and get my hands dirty. For anyone interested, you can refer this guide to install Amazon Q CLI. Basically Amazon Q CLI is like ChatGPT/Grok/DeepSeek but in the form of CLI, so it's quite easy to use as long as you are comfortable with CLI environment. So with Amazon Q CLI ready, now is time for prompting! It's working better than I expected as it appears Q is using a reasoning model by default, though the response time could be quite long as a trade-off. Therefore, after endless prompting and revising, i find the below tips that maybe usefull in facilitating effective prompting and reduce the back-and-forth between you and Q: Define a prompting framework such that the Q know the context, the task, and the expected results Ask Q to provide visual debugs can let the Q know how to fix issues more quickly Ask Q to give a plan before coding, that way you know Q is thinking as you expected With about 3 hours prompting and waiting, here's the final product! https://fbd.cmpapp.top GitHub: https://github.com/john-ng-hk/stem-fbd-game That's all and thanks for reading, feel free to connect me on LinkedIn too~  ( 3 min )

    **_How Excel is Used in Real-World Data Analysis_**
    Microsoft Excel is more than just a spreadsheet application—it’s a foundational tool that transforms raw data into meaningful insights. From simple lists to complex data models, Excel provides a flexible environment for organizing, analyzing, and visualizing information across industries and disciplines. PivotTables: These allow me to summarize and analyze large datasets quickly. For example, I used a PivotTable to count product entries by rating category and discount level, helping me uncover patterns in pricing strategies. IF Function: The =IF () formula is incredibly useful for categorizing data. I applied it to group products into “Excellent,” “Average,” and “Poor” rating categories based on numeric thresholds, which made my dataset more meaningful. Data Sorting and Filtering: By combining Excel’s sorting tools with slicers, I was able to isolate top-performing products based on ratings, reviews, and discounts. This made it easier to create targeted visualizations and focus my analysis on what matters. Conditional Formatting: This feature highlights cells based on criteria, like coloring cells red for values below a threshold. It’s ideal for spotting outliers in financial data or tracking project deadlines. Learning Excel has completely reshaped how I view data. What once seemed like overwhelming numbers in rows and columns now feels like a story waiting to be uncovered. Excel has taught me that with the right tools, I can dig beneath the surface of data to find insights that are not only informative but transformative. It’s made me more curious, more confident, and more equipped to approach challenges—one cell at a time.  ( 4 min )

    Exploring the `@Attribute` Decorator in Angular 🔍
    Hey devs! 👋 During a recent discussion with some colleagues about TypeScript decorators, we ended up deep-diving into Angular.dev and stumbled upon something interesting — the @Attribute decorator. Though it's not as commonly used as @Input, it's a powerful and underutilized feature in Angular. So, I wanted to take a moment to share what I learned about it, along with a real-world example. 🚀 @Attribute in Angular? The @Attribute decorator is a parameter decorator used in a directive's constructor to inject a host element's attribute value as a static string. It allows a class (typically a directive or component) to access a static HTML attribute value at construction time, even if it’s not bound to an Angular input. ✅ Great for static values from HTML attributes 🚫 Not reactive (doesn’…  ( 5 min )

    When Databricks announced Lakebase, most people dismissed it as just another product. Even Databricks markets it as "the backend for AI Agents and Data Apps." This messaging puzzles me. It's the same pattern they followed with Delta Lake in 2019, positioning it as "bringing reliability to Big Data." But Delta Lake was actually much simpler: a transactional layer on top of an immutable object store. That's it. Yet this simple concept solved a massive architectural challenge—enabling storage and compute separation for data warehouses at scale. Storage and compute separation became the foundation for everything that followed: data sharing, unified storage formats, multiple query engines. But separation creates a problem: latency. For analytical workloads, this latency is manageable. For trans…  ( 4 min )

    Why I Built a Self-Hosted Chat Automation Platform?
    Most chat automation tools today are SaaS - easy to get started with, but quickly limiting when you need flexibility, control, or cost efficiency. I built WhautoChat because I kept running into the same problems: 💸 Rising Costs: Pricing grows fast with usage. 🔒 Lack of Data Control: Sensitive customer data sits on someone else's servers. 🧱 Feature Lock-In: Basic features hidden behind expensive plans. So I built a self-hosted, omnichannel chat automation platform that works across WhatsApp, Telegram, Messenger, and Instagram. It includes: Custom AI bots (GPT-powered) Broadcasts Automation rules Team inbox Real-time API and webhook support No lock-ins. No recurring SaaS fees. Just full control. If you're a dev, agency, or business tired of limitations, self-hosting might be worth considering. Happy to share more if you're curious.  ( 3 min )

This decision impacts how you'll load and display them. Having a clear process for getting images into your Flutter project will save you headaches down the road. Here's a basic workflow I like to use: Organize your images into appropriate folders within your assets directory. Update your pubspec.yaml file to declare these asset folders.

    Identifying Stored Procedures Created or Modified Within a Date Range in SQL Server
    As part of rewriting the documentation for my custom API, I needed to test each endpoint to ensure it behaved as expected, including validating both input and output.

    Clone Eloquent Models Selectively
    Sometimes, you may need to duplicate a model instance and create a new one with some custom changes. Instead, you can use Laravel's built-in replicate method: use App\Models\Address; $shipping = Address::create([ 'type' => 'shipping', 'line_1' => '123 Example Street', 'city' => 'Victorville', 'state' => 'CA', 'postcode' => '90001', ]); // Create a replicated instance of the address without saving it $replicatedAddresss = $shipping->replicate(); The previous code creates a new address instance but does not save it to the database. Before saving, you can modify any attributes as needed: ... $replicatedAddresss->type = 'billing'; // Save the replicated instance to the database $replicatedAddresss->save(); Alternatively, you can replace the previous line where the property is assigned with the fill method: ... $replicatedAddresss = $shipping->replicate(); $replicatedAddresss->fill(['type' => 'billing'])->save(); On top of that, you can exclude specific attributes from being replicated by passing them as an array to the replicate method: $shipping = Address::create([ 'type' => 'shipping', 'line_1' => '123 Example Street', 'city' => 'Victorville', 'state' => 'CA', 'postcode' => '90001', ]); $shipping->replicate([ 'line_1', 'state' ]);  ( 3 min )

    Generate Playwright Tests Without Code Access Using MCP and Copilot
    Getting GitHub Copilot to write end-to-end tests usually requires giving it access to your source code. That’s because Copilot on its own can’t open a browser, explore a webpage, or understand how a UI behaves, so it lacks the context needed to generate accurate tests. But that changes with Playwright MCP (Model Context Protocol). An MCP acts as a bridge between Copilot and the real browser, allowing it to open websites, interact with UI elements, and take snapshots of the page. This unlocks a whole new capability: generating Playwright tests from natural language instructions, even when you don’t have access to the application’s codebase. In this post, we’ll show how Copilot, with the help of the Playwright MCP, can generate, run, and validate E2E tests just by telling it what you want in…  ( 5 min )

    🏗️ DEMOLISH THE GIANT: META — The Metaverse That Never Was
    Welcome to Week 3 of the "Demolish the Giant" series. This week, we dive into Meta — the company that bet big on a future in virtual reality but ended up chasing ghosts in a laggy metaverse. Mark Zuckerberg, a visionary with relentless ambition, plunged Meta into the metaverse era with Oculus and billions in investment. He saw a future where virtual worlds would replace real ones. But dreams don’t always sync with reality — especially when your VR legs feel like spaghetti. His obsession? Creating a new internet where you live inside the screen, not just look at it. Meta poured billions into VR hardware, software, and social platforms. They built Horizon Worlds — a VR social network that promised endless possibilities. But here’s the catch: users stayed skeptical. Technical glitches, lack of content, and a general feeling of awkwardness kept the metaverse niche at best. Meta’s metaverse was more of a phantom limb than a new reality. While the metaverse lagged, Meta doubled down on collecting your data. VR headsets track every glance, every gesture, every moment of attention. Privacy advocates warn that this level of surveillance inside virtual worlds could become the ultimate data trap. Meta’s real metaverse might be the invasion of your personal space and mind. With the metaverse hype deflating, Meta is pivoting quietly back to its core: social media and AI. But the question remains — can a company so invested in a VR dream admit defeat? Or will Meta keep chasing shadows in virtual worlds while reality moves on? Meta’s metaverse is a cautionary tale of ambition without timing. A vision that’s more glitch than game changer. Mark’s dream to live inside the internet faces a harsh reality: the real world still wins — for now. ✨ Coming Next Week: AMAZON — The Invisible Empire Where convenience meets surveillance and the warehouse meets your doorstep. Stay vigilant. Stay critical. Let the demolition continue.  ( 4 min )
    CSS Container Queries Tutorial for Beginners
    CSS container queries are a powerful feature that allows you to style elements based on the size of their parent container, rather than the entire viewport.
